Systematic structural and anisotropy of magnetic susceptibility (AMS) measurements were carried out on Cenozoic clay-rich deposits from the Transdanubian Range, central part of the Alcapa Unit. The aim was to improve the knowledge of the Neogene tectonic evolution of the area and of the connection of the stress field and the magnetic fabric of the sediments. The measurements of AMS revealed dominant foliation with weak lineation for Middle Eocene-Lower Miocene sediments. The directions of AMS lineation are aligned either with the direction of NNE-SSW extension of a strike slip phase (30–19 Ma) or with the direction of NE-SW extension of the main rifting phase of the Pannonian Basin (19–14 Ma).The studied Late Miocene sediments have foliated AMS fabric, maximum and intermediate AMS directions are intermixed, and the AMS fabrics do not show any sign of tectonic deformation. In contrast, joints and faults were observed in the same rocks. Detailed structural analysis shows two extensional phases between ca. 1...
对阿尔卡帕单元中部跨多瑙河山脉新生代富粘土矿床进行了系统的结构和各向异性磁化率(AMS)测量。目的是提高对该地区新近纪构造演化的认识,以及对应力场与沉积物磁性结构的联系的认识。AMS测量结果显示,中始新世-中新世下沉积物的面理作用明显,线理作用弱。AMS线理方向与走滑期北北东—南南西伸展方向(30 ~ 19 Ma)或潘盆期主裂陷期北东—南南西伸展方向(19 ~ 14 Ma)一致。所研究的晚中新世沉积物具有片理的AMS组构,最大和中间方向混杂,AMS组构未表现出构造变形的迹象。相反,在同一岩石中观察到节理和断层。详细的构造分析表明,在约1…

Numerous accumulations of CO2 and nitrogen-rich natural gas are known in the hot Pannonian Basin System (PBS), where even the mixture of these two fluids is a common phenomenon. The Danube Basin, part of the PBS, is characterized by the predominance of CO2 and nitrogen-rich natural gas over “normal” natural gas. The multistacked Repcelak and Mihalyi gas accumulations (southern, Hungarian part of the Danube Basin) display an upward increase of nitrogen-rich natural gas at the expense of CO2. This study, using the abundant public data, the published results and the new biomarker data obtained from oil traces, attempts to explain the formation of these multistacked accumulations. A synoptic view of the vertical changes in gas composition, the maturation history of the basin and its basement, the chronology of the Neogene basaltic volcanism and the biomarker pattern of the oil traces resulted in the recognition of the metasedimentary origin of the nitrogen-rich natural gas and in a relative chronology of the ...
在炎热的潘诺尼亚盆地系统(PBS)中,已知有大量的二氧化碳和富氮天然气聚集,甚至这两种流体的混合物也是一种常见现象。多瑙河盆地是PBS的一部分,其特点是富含二氧化碳和氮的天然气比“普通”天然气更占优势。多层Repcelak和Mihalyi天然气聚集(多瑙河盆地匈牙利部分的南部)显示出富氮天然气的上升,而二氧化碳的增加则为代价。本研究利用大量的公开数据、已发表的研究结果以及从油迹中获得的新的生物标志物数据,试图解释这些多层叠成藏的形成。通过对天然气组成的纵向变化、盆地及其基底的成熟历史、新近系玄武岩火山作用年代学和油迹生物标志物模式的综合分析,确定了富氮天然气的变质沉积成因,并确定了富氮天然气的相对年代学。

Crystal inclusions (plagioclase, biotite, magnetite) and melt inclusions were studied in minerals of the Laleaua Albă dacite (Baia Sprie, Romania). Electron microprobe analysis of 29 melt inclusions in the plagioclase, K-feldspar, and quartz confirm that crystallization of these minerals took place from typical silicic melts enriched in potassium relative to sodium (K2O/Na2O = 1.5). The sum of the petrogenic components is 92–99 wt%. This points to a possible change in water content from 8 to 1 wt% during crystallization of phenocrysts. According to ion microprobe analysis of 11 melt inclusions, the minimum water content is 0.5 wt%, and the maximum water content is 6.1 wt%. The presence of high-density water fluid segregation in one of the melt inclusions suggests that the primary water content in the melt could reach 8.4 wt%. Ion microprobe data revealed a high concentration of Cu (up to 1260 ppm) as well as higher U content (from 5.0 to 14.3 ppm; average 11.5 ppm) in some melt inclusions as compared to t...
研究了罗马尼亚Baia Sprie Laleaua albuei英安岩矿物中的晶体包裹体(斜长石、黑云母、磁铁矿)和熔融包裹体。对斜长石、钾长石和石英中29个熔体的电子探针分析证实,这些矿物的结晶发生在典型的富钾(K2O/Na2O = 1.5)硅熔体中。产岩组分的总和为92% ~ 99%。这表明在结晶过程中,水分含量可能从8%变化到1%。通过离子探针对11个熔体包裹体进行分析,发现其最小含水量为0.5 wt%,最大含水量为6.1 wt%。其中一个熔体包裹体中存在高密度的水流体偏析,表明熔体中的初级含水量可达8.4%。离子探针数据显示,铜的浓度很高(高达1260 ppm), U的含量也较高(从5.0到14.3 ppm;在一些熔体夹杂物中平均11.5 ppm),相比之下…

The birth of urban geologic maps (which are considered environmental-geologic themed maps) and the progress in development of their content and design were driven by the growing importance of addressing environmental problems, and the increasing complex utilization of urban areas. Therefore, MAFI and, since 2012, the MFGI Department of Environmental Geology, have prepared a series of maps for the local authorities of Budapest. These maps usually focus on the problems of urban planning from the viewpoint of geology, hydrogeology, and water chemistry, and as experience shows, they prove to be excellent tools in decision-making processes. This paper examines the chemical content of groundwater, which is one of the main indicators of the state of the environment. According to the everyday experience of the authors it is very useful to understand the state of both quality and quantity of subsurface and surface water. In a recent series of research work we measured the zinc, copper, boron and arsenic level of t...
城市地质图(被认为是环境地质主题地图)的诞生及其内容和设计的发展进步是由解决环境问题日益重要和城市地区日益复杂的利用所驱动的。因此,自2012年以来,MAFI和MFGI环境地质部为布达佩斯地方当局准备了一系列地图。这些地图通常从地质学、水文地质学和水化学的角度关注城市规划问题,经验表明,它们是决策过程中的优秀工具。地下水化学成分是反映环境状况的主要指标之一,本文对地下水化学成分进行了研究。根据作者的日常经验,了解地下水和地表水的质量和数量状况是非常有用的。在最近的一系列研究工作中,我们测量了t的锌、铜、硼和砷含量。

A field experiment with microelement loads was set up on loamy-textured, calcareous chernozem soil formed on loess. The ploughed layer contained about 5% CaCO3 and 3% humus. The soil was well supplied with Ca, Mg, Mn and Cu, moderately supplied with N and K, and weakly supplied with P and Zn. The water table is at the depth of 15 m, the water-balance of the area is negative, and the site is drought-sensitive. Salts of the 13 examined microelements were applied at 4 levels in the spring of 1991.Treatments were arranged in split-plot design, in a total of 104 plots with two replications. Loading rates were 0, 90, 270 and 810 kg/ha per elements in the form of AlCl3, NaAsO2, BaCl2, CdSO4, K2CrO4, CuSO4, HgCl2, (NH4)6Mo7O24, NiSO4, Pb(NO3)2, Na2SeO3, SrSO4, and ZnSO4. Soil profiles of the control and the 810 kg/ha treatment were sampled in the 3rd, 6th and 10th year of the trial. The mixed samples, consisting of 5 cores/plot, were taken every 30 cm to the depth of 60 (1993), 90 (1996) and 290 (2000) cm. NH4-ac...

The aim of this paper is to examine the relationship between soil properties and potentially toxic element contents of arable soils based on the dataset of the Soil Information and Monitoring System in Hungary. Nine potentially toxic elements (As, B, Cd, Co, Cr, Cu, Ni, Pb, Zn) were compared with selected soil parameters. We carried out grouping of related soil properties by principal component analysis. The method was suitable to describe the relationship within groups of the soil properties. We studied correlations of the resulting components and potentially toxic elements. The change of Ni content was influenced by the physical properties of the soil (e.g. clay content, field capacity, R = 0.67). Boron is the only one of the examined elements that indicates significant positive correlation with saline-alkali (R = 0.21) parameters. Zn, Co and Cr behaved very similarly; their correlation with components 1 and 2 were the closest.
本文的目的是根据匈牙利土壤信息和监测系统的数据集,研究土壤性质与耕地土壤潜在有毒元素含量之间的关系。9种潜在有毒元素(As, B, Cd, Co, Cr, Cu, Ni, Pb, Zn)与选定的土壤参数进行了比较。采用主成分分析法对相关土壤性质进行分组。该方法适用于描述土壤性质组间关系。我们研究了产生的成分和潜在有毒元素的相关性。Ni含量的变化受土壤物理性质(如粘土含量、田间容量,R = 0.67)的影响。硼是唯一与盐碱参数呈显著正相关的元素(R = 0.21)。Zn、Co和Cr的表现非常相似;它们与成分1和成分2的相关性最密切。

South of the Sudetes and Tatra Mountains young sediments contain more of almost all micro- and mesoelements than those to the north of the Carpathian Mountains, which were covered by ice during the Late Pleistocene. As detailed investigations show this larger unit is a collection of many individual geochemical regions, among which there are four on the area of Hungary: the region of soil calcification in the central part of Hungary, the slope debris of the foothills of the Eastern Alps, the floodplains of the rivers of Eastern Hungary that are contaminated with the waste material of heavy industry, and the rest of the country. No general geochemical background can be given to the whole; the background value intervals for each element shall be given for each geochemical region separately. In Eastern Hungary, where those rivers flow that originate from the heavy industrial centers of Transylvania and Slovakia, the toxic elements can locally exceed the limit value.

The health risks of consuming drinking water with elevated arsenic content of geochemical origin 饮用地球化学来源砷含量升高的饮用水的健康风险

High concentration of naturally-occurring arsenic in groundwater poses a significant risk to human health if this water is a drinking water resource. Chronic arsenic ingestion has been linked mainly to skin cancer, and a wide variety of non-cancer health impacts. Research conducted in Hungary shows that there is an excessive risk of arsenic-related diseases in populations consuming water that exceeds the 10 microgram/liter limit value. It is therefore important to understand the significance of reduction of arsenic concentration in drinking water and the size of the exposed population.
如果地下水是一种饮用水资源,那么地下水中天然存在的高浓度砷将对人类健康构成重大风险。长期摄入砷主要与皮肤癌以及各种各样的非癌症健康影响有关。在匈牙利进行的研究表明,饮用超过10微克/升限值的水的人群患与砷有关的疾病的风险过高。因此,了解降低饮用水中砷浓度的意义和接触人群的规模是很重要的。

Knowledge of the distribution and sorption characteristics of trace metals in soils is essential because of their importance both from agricultural and environmental point of view. In this paper, an overview will be provided on the relationship between the behavior and sorption properties of Cu and Pb as well as major soil characteristics, based on the results obtained by several independent research projects carried out on this field at the Institute for Geological and Geochemical Research over the last 15 years. These projects were accomplished using methods with different approaches, e.g. studying metal characteristics by total metal content, selective chemical extractions and batch sorption experiments.Our results show that both metals can be found in soils, primarily in the form of phases highly resistant to weathering. However, if they are mobilized, they are easily and strongly immobilized by soils rich in organic matter, with higher affinity for Cu than for Pb. In acid soils, on the other hand, th...
了解土壤中微量金属的分布和吸附特性是必不可少的,因为从农业和环境的角度来看,它们都很重要。本文将根据中国地质与地球化学研究所近15年来在该领域开展的几个独立研究项目的成果,综述铜和铅的行为和吸附性质以及主要土壤特征之间的关系。这些项目采用了不同的方法来完成,例如通过总金属含量研究金属特性,选择性化学萃取和批量吸附实验。我们的研究结果表明,这两种金属都可以在土壤中找到,主要以高度抗风化的相的形式存在。然而,如果它们被动员起来,它们很容易被富含有机质的土壤强烈固定,对Cu的亲和力高于对Pb的亲和力。另一方面,在酸性土壤中,…
