Remains of a vast Roman pottery production complex were found on the shore of the Plemi ć i Bay (Op ć ina Ražanac, Zadar county) in 2012, and confirmed by geophysical survey. Ground-penetrating radar measurements revealed outline of a rectangular building that finds analogies with Roman storehouses ( horreum ). The area occupied by remains of the Roman pottery workshop was covered by immense soil-debris flows. Three geological exposures located to the north of the remains of the Roman building were documented using lithological and malacological analysis, and magnetic susceptibility measurements. The profiles revealed at least three generations of slope sediments, formed in result of intensive soil or debris flows in a dry climate, most probably in 5 th c. AD. In the next, wet phase sediments were transported downslope and deposited on the Roman structures after 5 th c. AD. Environmental conditions at Pelmi ć i were supply with paleoclimate evidence from the Adriatic region. At ca. 1.5 cal. BP lake levels in the eastern Adriatic area were drastically reduced, probably because of strong decrease in humidity, correlated with the so-called North Atlantic Bond event 3. The drought was followed by a humid episode, also attested at the Plemi ć i archaeological site.
2012年,在Plemi č i湾(Op č ina Ražanac, Zadar县)海岸发现了一个巨大的罗马陶器生产遗址,并经地球物理调查证实。探地雷达测量显示了一个矩形建筑的轮廓,与罗马的仓库(horreum)相似。罗马陶器作坊遗址所在的区域被巨大的土壤碎屑流所覆盖。通过岩石学和malacology分析以及磁化率测量,研究人员记录了位于罗马建筑遗迹北部的三个地质暴露点。剖面显示了至少三代斜坡沉积物,它们是在干燥气候下由密集的土壤或泥石流形成的,最有可能是在公元5世纪。公元5世纪以后,湿相沉积物被运下坡并沉积在罗马构造上。Pelmi č i的环境条件提供了来自亚得里亚海地区的古气候证据。在大约1.5 cal. BP时,亚得里亚海东部地区的湖泊水位急剧下降,可能是因为湿度的强烈下降,这与所谓的北大西洋Bond事件有关。干旱之后是湿润期,这在普莱米奇考古遗址也得到证实。

This paper presents the Late Glacial stage of the development of the Białe Ługi peatland in the southern Holy Cross Mountains, based on a comprehensive palaeoenvironmental data. A complex analysis of palynology, Cladocera, sedimentology, geochemistry and 14C dating were used. Organic deposition was initiated during the Oldest Dryas. The sedimentary record of the aquatic and terrestrial ecosystems reflects considerable difference between cooler (Oldest, Older and Younger Dryas) and warmer phases (Bølling and Allerød). Periods of intensified interaction between aeolian processes and peatland are related to stages of disappearing vegetation and changes in aquatic invertebrate communities. We therefore suggest that peatlands were created as a result of local lithological-structural, tectonic, hydrogeological and morphological conditions, and the peatland development rate was largely influenced by changing climatic conditions, which determined local vegetation development, intensity of denudation processes and water level changes. The results validate significance of selection and use of several methods, as well as value of biogenic deposits from the Białe Ługi peatland as archives of past climate change in the Małopolska Upland. Relatively stable water conditions and uninterrupted biogenic sedimentation in the Late Glacial that were provided by the geological structure and relief suggest the studied peatland is a leading one in the region.
本文在综合古环境资料的基础上,提出了圣十字山南部Białe Ługi泥炭地发育的晚冰期。采用孢粉学、枝角学、沉积学、地球化学和14C测年等综合分析方法。有机沉积是在最古老的仙女木时期开始的。水生和陆地生态系统的沉积记录反映了较冷阶段(最老、较老和较新仙女木期)和较暖阶段(Bølling期和Allerød期)的显著差异。风成过程与泥炭地相互作用加剧的时期与植被消失的阶段和水生无脊椎动物群落的变化有关。因此,泥炭地的形成是当地的岩性构造、构造、水文地质和形态条件共同作用的结果,而泥炭地的发育速度在很大程度上受气候条件变化的影响,气候条件的变化决定了当地植被的发育、剥蚀过程的强度和水位的变化。结果验证了几种方法的选择和使用的意义,以及Białe Ługi泥炭地生物沉积物作为Małopolska高地过去气候变化档案的价值。地质构造和地形为该区提供了相对稳定的水条件和晚冰期不间断的生物沉积,表明该区泥炭地是该区领先的泥炭地。

According to the current state of research five sand-gravel accumulation levels of Quaternary age are visible in the morphology of the western part of the Holy Cross Mountains, within the Wierna Rzeka, Hutka and Bobrza river valley systems and the lower stretches of the Biała Nida and Czarna Nida river valleys. Two upper levels (V and IV) correspond to valleys formed during the Odranian Glaciation-Saalian, MIS6 and its reccesional phases under the influence of proglacial and extraglacial waters beyond the extent (to the east) of the maximal ice-sheet limit of this glaciation, reaching to the present-day Leśnica-Gnieździska-Łopuszno line. Two lower levels (III and II) are terraces that were typically formed during the climatic conditions thatprevailed during Vistulian stadials. Sands and gravels of the three upper levels (V−III) contain numerous debris flow deposits and cryoturbation structures documenting periglacial conditions during their accumulation. The lowermost level (I) is a typical Holocene floodplain.
根据目前的研究情况,在圣十字山西部、Wierna Rzeka、Hutka和Bobrza河谷系统以及Biała Nida和Czarna Nida河谷下游,可以看到五个第四纪的砾石堆积水平。较高的两个层(V和IV)对应于奥德兰冰期-萨利安冰期、MIS6冰期及其消退阶段在原冰期和冰外水的影响下形成的山谷,超出了该冰期最大冰盖极限的范围(向东),达到今天的Leśnica-Gnieździska-Łopuszno线。较低的两层(III级和II级)是典型的在维斯图拉时期气候条件下形成的梯田。砂和砾石的三个上层(V - III)含有大量的泥石流沉积物和低温扰动结构,记录了它们在堆积过程中的冰周条件。最底层(I)为典型的全新世洪泛平原。

: This study presents the results of a comprehensive geoarchaeological study implemented at an archeological site covering ca. 5 ha near the city of Csorna on the NW part of the Danube Plain, NW Hungary. The site itself exposed a complex fluvial system of an ice age creek with near bank and overbank areas (levee, point bar, back swamp). Spatial distribution of archeological features allowed for the interpretation of differential use of the fluvial landscape by different cultures. According to our data, the referred fluvial system must have emerged during the Late Glacial. At this time, creeks orig-inating from hills to the SE followed a uniform NW trajectory. From the Holocene, small creeks were beheaded turning into inactive flood channels. It was the time when the gradual infilling of the floodplain started. Alternating layers of floodwater coarses and floodplain fines mark recurring floods at our site. These could have been correlated with cooler, wetter climatic phases of the North Atlantic, Western Europe and high stands in Central European lakes. Highest floods are recorded during the Late Bronze and Iron Ages besides the Neolithic. Pollen data enabled us to make inferences on the vegetation as well.
本研究介绍了在匈牙利西北部多瑙河平原西北部科索尔纳市附近一个占地约5公顷的考古遗址进行的一项综合地质考古研究的结果。该遗址本身暴露了一个复杂的冰河时代溪流系统,靠近河岸和河岸地区(堤坝,点坝,后沼泽)。考古特征的空间分布可以解释不同文化对河流景观的不同利用。根据我们的资料,上述河流系统一定是在晚冰期出现的。在这个时候,从丘陵到东南的小溪沿着一个统一的西北轨迹。从全新世开始,小溪被切断,变成了不活跃的洪道。那时洪泛区开始逐渐被填满。洪水粗层和洪泛区细层交替出现,标志着我们的场地经常发生洪水。这可能与北大西洋、西欧和中欧湖泊高地较冷、较湿的气候阶段有关。除了新石器时代外,铜器时代晚期和铁器时代也有最高的洪水记录。花粉数据也使我们能够对植被做出推断。

Abstract The site at Orłowo Cliff was used to analyse the stratigraphic position and palaeogeographic interpretations of the properties and depositional conditions of two basal tills from the Late Pleistocene. A multi-proxy approach involved lithofacies, petrographic analysis of the fine gravel fraction, analyses of indicator erratics and till fabric. TL dating of intra-moraine deposits was used to determine depositional time frames of tills. The sediment profile at Orłowo Cliff shows a distinct reduction in number of Pleistocene units. Obtained dating results suggest the presence of Middle and Late Pleistocene fluvial units. The main issue discussed is the stratigraphic position of the older till (Unit O-4). It can be assumed that this till was deposited probably during the Middle Weichselian (MIS4). At Orłowo Horn the till of Unit O-4 reveals incorporation of the erratic material derived from an older till in the surrounded area (according to petrographic composition - probably from MIS 8). The younger till (Unit O-6) was deposited in the Late Weichselian (MIS 2). Moreover, the till of Unit O-6 is characterised by a significant shift towards the south-west in terms of the erratic origin in Unit O-4.
摘要奥沃崖遗址用于分析晚更新世两个基丘的地层位置和古地理特征及沉积条件。一种多代理方法涉及岩相、细砾石组分的岩相分析、指示误差分析和泥质组构分析。冰碛内沉积物的TL测年用于确定tills的沉积时间框架。Orłowo悬崖的沉积物剖面显示更新世单元数量明显减少。测年结果表明存在中更新世和晚更新世的河流单元。讨论的主要问题是老til(单元O-4)的地层位置。可以推测,该矿床可能是在中魏氏时代(MIS4)沉积的。在Orłowo Horn,O-4单元的收银台显示,周围地区的旧收银台中含有不稳定的物质(根据岩相组成,可能来自MIS 8)。晚稻(O-6单元)沉积于晚魏克塞尔阶(MIS 2)。此外,就O-4单元的不稳定起源而言,O-6单元的收银台的特征是向西南方向显著移动。

Cosmic Airburst on Developing Allerød Substrates (Soils) in the Western Alps, Mt. Viso Area 宇宙气暴对西阿尔卑斯、Viso山地区过敏原基质(土壤)发育的影响
IF 0.6 Q3 Earth and Planetary Sciences Pub Date : 2018-06-01 DOI: 10.2478/squa-2018-0001

Abstract Although much has been written about a cosmic impact event in the Western Alps of the Mt. Viso area, the event closely tied with the Younger Dryas Boundary (YDB) of 12.8 ka and onset of the Younger Dryas (YD), the affected land surface is considered to contain a similar black mat suite of sediment found on three continents. While work elsewhere has focused on recovered sediment from lake and ice cores, buried lacustrine/alluvial records, and surface glacial and paraglacial records, no one has traced a mountain morphosequence of deposits with the objective of investigating initial weathering/ soil morphogenesis that occurred in ice recessional deposits up to the YDB when the surface was subjected to intense heat, presumably, as hypothesized by Mahaney et al. (2016a) from a cosmic airburst. With the land surface rapidly free of ice following glacial retreat during the Bølling-Allerød interstadial, weathering processes ~13.5 to 12.8 ka led to weathering and soil morphogenesis in a slow progression as the land surface became free of ice. To determine the exposed land character in the mid- to late-Allerød, it is possible to utilize an inverted stratigraphic soil morphogenesis working backward in time, from known post-Little Ice Age (LIA) (i.e. time-zero) through LIA (~0.45 to ~0.10 ka), to at least the middle Neoglacial (~2 ka), to answer several questions. What were the likely soil profile states in existence at the end of the Allerød just prior to the cosmic impact/airburst (YDB)? Assuming these immature weathered regolith sections of the Late Allerød approximated the <1 ka old profiles seen today, and assuming the land surface was subjected to a hypothesized instant temperature burst from ambient to ~2200°C at ~12.8 ka, what would be the expected effect on the resident sediment? To test the mid-LG (YDB) to YD relationship we analyzed the paleosols in both suites of deposits - mid-LG to YD - to test that the airburst grains are restricted to Late Allerød paleosols and using relative-age-determination criteria, that the overlapping YD to mid-LG moraines are closely related in time. These are some of the questions about the black mat that we seek to answer with reference to sites in the upper Guil and Po rivers of the Mt. Viso area.
虽然关于Viso山西阿尔卑斯地区的宇宙撞击事件已经写了很多,该事件与12.8 ka的新仙女木边界(YDB)和新仙女木(YD)的开始密切相关,但受影响的陆地表面被认为包含在三个大陆上发现的类似的黑色垫层沉积物。虽然其他地方的工作主要集中在从湖泊和冰芯中回收的沉积物,埋藏的湖泊/冲积记录,以及表面冰川和副冰川记录,但没有人追踪沉积物的山脉形态序列,目的是研究地表受到高温时发生在YDB的冰消退沉积物中的初始风化/土壤形态形成,这可能是Mahaney等人(2016a)从宇宙空气爆炸中假设的。在b ølling- allero ød间冰期,随着冰川退缩,陆地表面迅速无冰,~13.5 ~ 12.8 ka的风化过程导致了陆地表面逐渐无冰的风化和土壤形态形成。为了确定alallerd中晚期的暴露土地特征,可以利用反向地层土壤形态发生的时间回溯,从已知的小冰期(LIA)(即时间零)到LIA (~0.45 ~ ~0.10 ka),至少到新冰期中期(~2 ka),来回答几个问题。在宇宙撞击/空气爆炸(YDB)之前,在Allerød结束时可能存在的土壤剖面状态是什么?假设这些晚期allero ød的未成熟风化风化剖面近似于今天看到的<1 ka旧剖面,并且假设地表在~12.8 ka时遭受了一个假设的瞬间温度从环境温度上升到~2200°C,那么对常驻沉积物的预期影响是什么?为了验证中lg (YDB)与YD的关系,我们对中lg—YD两套沉积物的古土壤进行了分析,验证了气爆颗粒局限于晚Allerød古土壤,并利用相对年龄测定标准验证了重叠的YD—中lg冰碛在时间上密切相关。这些都是关于黑垫的一些问题,我们试图通过参考Mt. Viso地区的Guil河上游和Po河来回答这些问题。

Viso area, the event closely tied with the Younger Dryas Boundary (YDB) of 12.8 ka and onset of the Younger Dryas (YD), the affected land surface is considered to contain a similar black mat suite of sediment found on three continents. While work elsewhere has focused on recovered sediment from lake and ice cores, buried lacustrine/alluvial records, and surface glacial and paraglacial records, no one has traced a mountain morphosequence of deposits with the objective of investigating initial weathering/ soil morphogenesis that occurred in ice recessional deposits up to the YDB when the surface was subjected to intense heat, presumably, as hypothesized by Mahaney et al. (2016a) from a cosmic airburst. With the land surface rapidly free of ice following glacial retreat during the Bølling-Allerød interstadial, weathering processes ~13.5 to 12.8 ka led to weathering and soil morphogenesis in a slow progression as the land surface became free of ice. To determine the exposed land character in the mid- to late-Allerød, it is possible to utilize an inverted stratigraphic soil morphogenesis working backward in time, from known post-Little Ice Age (LIA) (i.e. time-zero) through LIA (~0.45 to ~0.10 ka), to at least the middle Neoglacial (~2 ka), to answer several questions. What were the likely soil profile states in existence at the end of the Allerød just prior to the cosmic impact/airburst (YDB)? Assuming these immature weathered regolith sections of the Late Allerød approximated the <1 ka old profiles seen today, and assuming the land surface was subjected to a hypothesized instant temperature burst from ambient to ~2200°C at ~12.8 ka, what would be the expected effect on the resident sediment? To test the mid-LG (YDB) to YD relationship we analyzed the paleosols in both suites of deposits - mid-LG to YD - to test that the airburst grains are restricted to Late Allerød paleosols and using relative-age-determination criteria, that the overlapping YD to mid-LG moraines are closely related in time. These are some of the questions about the black mat that we seek to answer with reference to sites in the upper Guil and Po rivers of the Mt. Viso area.","PeriodicalId":42625,"journal":{"name":"Studia Quaternaria","volume":"35 1","pages":"23 - 3"},"PeriodicalIF":0.6,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43771831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Archaeology of north-eastern Poland has been poorly recognized owing to vast forest areas and numerous lakes. This particularly refers to the Warmian-Masurian Voivodship, where forest covers over 30% of its area. Prospection of forested areas has become possible in Poland just over 10 years ago with the Airborne Laser Scanning (ALS) and Light Detection and Ranging (LiDAR). These techniques allow obtaining 3-D documentation of recognized and also unknown archaeological sites in the forested areas. Thanks to ALS/LiDAR prospection a significant number of archaeological structures have been identified also in the Warmia and Masuria regions. Among them oval-shaped hillforts, surrounded by perfectly spaced concentric moats and ramparts, located mainly on islands and in wetland areas, have raised particular attention. Based on field prospection and results of preliminary excavations, these objects have been considered as Iron Age hillforts. One of the best preserved objects of this type is on the Radomno Lake island, located several kilometres to the south of Iława town. Integrated geoarchaeological prospection of this hillfort emphasized benefits of using LiDAR in combination with results of geophysical prospection and shallow drillings. Applied methodology enabled to document the hillfort shape, and to study its geological structure and stratigraphy. The results clearly indicate that integration of LiDAR data with geophysical prospecting is indispensable in future archaeological surveys. It is a perfect tool for remote sensing of archaeological objects in forest areas, so far not available for traditional archaeology.
波兰东北部的森林面积广阔,湖泊众多,考古工作一直未得到充分认识。这特别指的是沃姆-马苏里省,森林覆盖了其30%以上的面积。十多年前,波兰的机载激光扫描(ALS)和光探测和测距(LiDAR)技术使森林地区的勘探成为可能。这些技术使我们能够在森林地区获得公认的和未知的考古遗址的三维文件。由于ALS/LiDAR勘探,在Warmia和Masuria地区也发现了大量的考古结构。其中椭圆形的山堡,由间距完美的同心护城河和城墙包围,主要位于岛屿和湿地地区,引起了特别的关注。根据野外勘探和初步发掘结果,这些物品被认为是铁器时代的山堡。这类保存最完好的文物之一位于Iława镇以南几公里处的Radomno湖岛上。该山丘的综合地质考古勘探强调了将激光雷达与地球物理勘探结果和浅层钻探相结合的优势。应用方法记录了该山岭的形状,并对其地质构造和地层进行了研究。结果表明,在今后的考古调查中,激光雷达数据与物探数据的结合是必不可少的。它是目前传统考古无法获得的森林地区考古物遥感的理想工具。

Dave Henry Krinsley, colleague of many professionals and mentor to countless students over several decades, a man possessed of enormous scientific talent and ability, died quietly in his sleep on November 5, 2017, age 90. He had a long history at the University of Chicago, Cambridge University (UK), Queens (NY), Arizona State University (Tempe), finishing his days at the Department of Geological Sciences, University of Oregon and the laboratories of CAMCOR (Eugene). Beginning in the 1960’s Dave teamed up with others (Krinsley and Takahashi, 1962) to open the electron microscope to the analysis of sand grain textures as signatures of various environments, including experimental work on links between aeolian environments, and inherited surface microtextures on quartz sand. His later work with John Doornkamp (1973) at Nottingham resulted in the Atlas of Sand Grain Surface Textures, the first inventory of its kind that sparked a flurry of testing by Dave and others. This trial run period led to the principle of equifinality, that is, that some microtextures could be produced in multiple environments, so that only a few rare microtextures were endemic to just one environment. Subsequent work showed that multiple overprintings revealed vestiges of preweathering followed by several overprintings, relative ages judged on the basis of differential weathering of grain imprintings. While concentrating on aeolian signatures and lab ex pe rimentation, Dave moved from SE to BSE electron mi c ro scopy, on to TEM, STEM and FIB analyses, and to simulations of aeolian processes and expected grain microfeatures to be identified at some point on Mars (Krinsley et al., 1979). Add to this, Dave’s contribution of SEM microtexture grain analysis of different lithologies in sedimentary rocks of marine and terrestrial origin, and extended through time to the Precambrian, showed investigators how the electron microscope could shed light on geologic processes and environmental reconstruction through the vast expanse of geologic time. One of his latest papers, published in Scanning (Mahaney et al., 2016), demonstrated how combinations of STEM and FIB methods could be applied to weathering rinds, the combined analyses allowing microstratigraphic imaging and chemical analyses with depth, all shedding light on the black mat event as it affected the Western Alps 12.8 ka. His participation in the discovery of airburst related sediment, possibly black mat equivalent minerals in Antarctic paleosols, continued unabated right up to his passing. Dave is remembered also for his numerous papers on desert varnish, many done in conjunction with Ron Dorn at Tempe. Aside from his drive to understand geological processes and paleoenvironments, he is remembered as a man imbued with limitless curiosity that kept him in the lab right up to the end of his life. His associates at Arizona and Oregon remember him as an intellectual source that will be hard to replace and one from which they enjoyed
Dave Henry Krinsley是许多专业人士的同事,也是几十年来无数学生的导师,他拥有巨大的科学天赋和能力,于2017年11月5日在睡梦中悄然去世,享年90岁。他在芝加哥大学、剑桥大学(英国)、皇后区(纽约)、亚利桑那州立大学(坦佩)有着悠久的历史,在地质科学系、俄勒冈大学和CAMCOR(尤金)实验室度过了他的日子。从20世纪60年代开始,Dave与其他人(Krinsley和Takahashi,1962)合作,打开电子显微镜来分析作为各种环境特征的沙粒纹理,包括关于风成环境和石英砂继承表面微观结构之间联系的实验工作。他后来在诺丁汉与约翰·杜恩坎普(John Doornkamp,1973)合作,制作了《沙粒表面纹理图谱》,这是第一本此类目录,引发了Dave等人的一系列测试。这个试运行期导致了均衡性原则,即一些微文本可以在多个环境中产生,因此只有少数罕见的微文本在一个环境中是特有的。随后的工作表明,多个套印揭示了预风化的痕迹,随后是多个套印,相对年龄是根据颗粒印记的差异风化来判断的。在专注于风成特征和实验室实验的同时,Dave从SE转向BSE电子显微镜,转向TEM、STEM和FIB分析,并模拟风成过程和预计在火星上某个点识别的晶粒微观特征(Krinsley等人,1979)。除此之外,Dave对海洋和陆地沉积岩中不同岩性的SEM微结构颗粒分析的贡献,一直延伸到前寒武纪,向研究人员展示了电子显微镜如何在广阔的地质时代揭示地质过程和环境重建。他的一篇最新论文发表在《扫描》杂志上(Mahaney et al.,2016),展示了STEM和FIB方法的组合如何应用于风化皮,这些组合分析允许微观地层成像和深度化学分析,所有这些都揭示了影响12.8 ka西阿尔卑斯山的黑垫事件。在他去世之前,他一直参与发现与空气爆炸有关的沉积物,可能是南极古土壤中的黑垫等效矿物。Dave还因其在沙漠清漆方面的大量论文而被人们铭记,其中许多论文是与Ron Dorn在Tempe共同完成的。除了了解地质过程和古环境的动力外,人们还记得他是一个充满无限好奇心的人,这让他一直呆在实验室里,直到生命的尽头。他在亚利桑那州和俄勒冈州的同事们记得他是一个很难取代的智力来源,他们从中享受了一些令人兴奋的发现时光。

Abstract Palynological and archaeobotanical analyses were conducted on excavated sediments from Tse Dura, a Later Stone Age rock shelter in north-central Nigeria with the aim of reconstructing the environment conditions at the site within the last millennium. From 933 ± 29 BP to 802 ± 29 BP, the environment alternated between Guinea savanna with dry conditions, and secondary and riverine forests with humid conditions. During these periods of environmental fluctuations, the LSA populations engaged in the management of economic plants the most significant of which included Dioscorea spp. Pennisetum glaucum and Elaeis guineensis, and exploited wild plants such as Pavetta crassipes, Sarcocephalus latifolius and Lophira cf. lanceolata for dietary and ethnomedicinal purposes. Around 310 ± 30 BP cal, the environment became very wet after which it was succeeded by a drier period. It was during this period that Sorghum bicolor became prominent, and the environment attained its current status dominated by Guinea savanna elements and secondary forests.
摘要对尼日利亚中北部石器时代晚期岩石避难所Tse Dura的挖掘沉积物进行了考古学和古植物学分析,目的是重建该遗址上千年的环境条件。从933±29 BP到802±29 BP,环境在几内亚稀树草原干旱条件和次生林和河岸林潮湿条件之间交替。在这些环境波动的时期,LSA种群参与了经济植物的管理,其中最重要的包括薯蓣属植物。蓝盾叶狼尾草和盾叶狼蛛,并利用野生植物,如凤眼莲、宽叶Sarcoccephalus和Lophira cf.lanceolata,用于饮食和民族药用目的。在310±30 BP cal左右,环境变得非常潮湿,之后又经历了一段干燥期。正是在这一时期,双色高粱变得突出,环境达到了以几内亚稀树草原元素和次生林为主的现状。
