The relationship between the winter (DJFM) precipitation and the atmospheric circulation patterns is examined around Mount Olympus, Greece in order to assess the effects of orography and atmospheric dynamics over a small (less than 100 x 100 km) spatial domain. Winter accumulated rainfall datasets from 8 stations spread along the eastern (marine) and western (continental) sides of the Mount Olympus at elevations between 30 m and 1150 m are used during the period 1981 to 2000. Synoptic scale conditions of mean sea-level pressure and geopotential heights at 850 hPa and 500 hPa, were used to explain the multiyear rainfall variability. High pressure systems dominated over the central Mediterranean and most parts of central Europe during the late 1980’s and early 1990’s, are associated with minimum winter rainfall along both sides of Mount Olympus. The winter of 1996 was associated with peak in rainfall along the marine side of the mountain and was characterized by enhancement of upper level trough over the western Mediterranean and increased low tropospheric depressions over the southern Adriatic and the Ionian Seas. This atmospheric circulation pattern facilitated a southeasterly air flow that affected more (less) the marine (continental) sides of the mountain. In contrast, dominance of low pressure systems with cores over the Gulf of Genoa and the Central Mediterranean affect the study area mostly from west/southwest revealing higher correlations with the precipitation in the continental side of the mountain (r= -0.80; Elassona station) and considerably lower correlations with the marine side (r = -0.67; Katerini station). This highlights the orographic barrier of the Mount Olympus revealing large differences between the upward and leeward sides. Large scale atmospheric patterns like the North Atlantic Oscillation and the Arctic Oscillation seem to influence the winter rainfall in the lowlands along the continental side of the mountain.
研究了冬季降水与希腊奥林匹斯山周围大气环流模式之间的关系，以评估地形和大气动力学在小(小于100 x 100 km)空间域中的影响。1981年至2000年期间，分布在奥林匹斯山东部(海洋)和西部(大陆)两侧海拔30米至1150米之间的8个站点的冬季累积降雨量数据集被使用。用850 hPa和500 hPa的平均海平面压力和位势高度的天气尺度条件来解释多年降水变率。在20世纪80年代末和90年代初，高压系统在地中海中部和中欧大部分地区占主导地位，这与奥林匹斯山两侧冬季降雨量最少有关。1996年冬季与山脉海洋一侧的降雨高峰有关，其特点是地中海西部上空低槽增强，南部亚得里亚海和爱奥尼亚海上空对流层低气压增加。这种大气环流模式促进了东南气流，多(少)影响了山的海洋(大陆)一侧。相比之下，热那亚湾和地中海中部的低压系统主要从西/西南方向影响研究区域，表明与山大陆侧降水的相关性较高(r= -0.80;Elassona站)和与海洋侧的相关性相当低(r = -0.67;Katerini站)。这突出了奥林匹斯山的地形障碍，揭示了向上和背风面之间的巨大差异。像北大西洋涛动和北极涛动这样的大尺度大气模式似乎会影响山脉大陆一侧低地的冬季降雨。

Obsidian, a natural volcanic glass, was used extensively in ancient times because of its quality as a raw material for sharp blades. As such, obsidian is of high interest for provenancing studies, since reliable provenancing can provide information about trade routes, extension of territory, long-distance contacts and the mobility of prehistoric peoples. In general, well-established databases of the characteristic elemental composition, the chemical fingerprint, are needed for reliable provenancing. On Milos Island, two sources of raw obsidian, namely Agia Nychia (Cape Bombarda) and Demenegakion are known. Recent literature claims a third source close to Agios Ioannis. In a sampling expedition with the goal to complete the Atominstitut’s database on the chemical fingerprints of obsidian, samples at Agios Ioannis were collected to include this new source. At the location, 16 scattered samples were taken for analysis, even though no direct outcrop could be identified. On the nearby island Kimolos, several more samples were found. Using instrumental neutron activation analysis (INAA), the chemical fingerprint of the samples was measured and compared to the values in the database. All samples from Agios Ioannis were identified as either from Demenegakion or Agia Nychia, indicating that no further source of obsidian exists at the location.

From the widespread mineral exploitation of the past to the protected territory of the Sounion National Park in the present, the region of Lavreotiki has diachronically been at the centre of human activities and experiences. Nowadays, the landscape of the region, as defined by hills, valleys and the coastline at the SE of Attica, includes a variety of land uses, such as settlements (with prevailing traditional or contemporary styles), isolated properties (legal or illegal, inland or by the coast), agricultural lands (mainly vineyards and olive groves), uninhabited areas, roads, pathways and other transport routes, industrial units, tourist complexes, geological formations, archaeological and historical sites and landmarks, protected forest and shrub areas. However, the connecting element between them all has always been the large multi-metallic ore deposits found underground - their exploitation has shaped the landscape diachronically in a multitude of ways. This paper aims to explore the multiple facets of the landscape, interpret its characteristics as part of the diachronic heritage of the region and discuss its potential as an ‘off the beaten track’ place to visit.

The aim of this paper is to evaluate the effects of natural and synthetic zeolitic materials as soil amendments in contaminated soils. Two species of natural zeolites, clinoptilolite and mordenite, sampled from Samos Island, Greece, were used as low-cost modifiers (amendments). Both of these materials show perfect XRD-patterns. Moreover, coal fly ash (CFA) derived from the electrostatic precipitators of the Meliti power plant (Florina, Greece) converted via an alkaline hydrothermal treatment with 1M NaOH was used to produce a synthetic zeolitic material. The mineralogical composition of natural and synthetic zeolites was tested and identified by X-ray diffraction (XRD) and scanning electron microscope (SEM). The amendments and original contaminated soils from a former mining area of Lavrion, were mixed and equilibrated for 1 week, hydrated up to 40% of their water holding capacity. After the equilibration, the growth of Trifolium alexandrinum both in amended and original soils was studied in a pot experiment. The increase in pH value of treated soil by the tested amendments, confirmed the buffering effect and suggested the opportunity of using zeolitic materials for conditioning and remedying contaminated acidic soils from sulphidic mining areas. Moreover, the amended soils exhibited higher CEC values compared with unamended soil. Results showed that the synthetic zeolite produced by Meliti’s power station fly ash, was the most effective for plant growth, among the tested amendments. Between natural zeolitic materials from Samos Island, the most efficient was the clinoptilolite rich, probably because of its better water holding capacity compared with mordenite.

Greece holds significant amounts of lignite deposit, whose exploitation has been a major contributor to its energy development, to date. Lignite combustion produces gas pollutants, as by-products, which are emitted from the Thermo-Electrical Stations on daily basis and especially sulfur oxides, which can contribute to air pollution, if the appropriate preventive measures are not taken. Oxides’ capture is achieved using limestone, which is abundant in our country, provided that it fulfils certain standards. Therefore, it is deemed necessary to study the area surrounding the mineral deposit rocks, in order to create an excavation, the product of which is going to be used for the aforementioned purpose.

This is defined as “process stewardship”. Limited reference is also made to “product stewardship” activities associated with the downstream use of said products across their life cycle. The contribution made to local community and the infrastructure development to support parallel development of tourism and other activities is also described. The S&B mining stewardship in Milos Island subscribes fully to the S&B sustainable development goal and targets, to which reference is also made.

This paper studies the prehistoric use of obsidian quarries in the Aegean. Obsidian sources in the eastern Mediterranean have been traced on certain islands of the Aegean: Melos, Antiparos and Giali. Due to its hardness, this material was already being used by the end of the Upper Palaeolithic to produce blades with sharp edges to serve as knives, scrapers and razors, arrowheads and spears, axes, saws and mattocks. This naturally occurring glass was also used for ornamental purposes. During the Late and the Final Neolithic Period (ca. 5300-3200 B.C.), when the systematic habitation of the Cyclades developed, the transportation of obsidian was incorporated in the gradually developing trade networks of the Aegean. The material was much in demand in the early Bronze Age. During the later Bronze Age its use declined and by the classical period it seems to have been replaced by metal. Around 1100 B.C. the use of obsidian was discontinued because of the increasing popularity of metals. During the Roman period obsidian, was used in the manufacture of mosaics and decorative objects, such as mirrors

The possible exploitation of eastern Samos emery deposits during the antiquity is explored, taking into account the attested emery mining on the island, during the 19th and 20th c. A.D. Is it possible that Samos diasporitic emery had been used in a similar way with the diasporite and/or corundite emery of Naxos, the main and best known emery source in the Aegean archipelago? As a first step for the investigation of this question, existing geological and historical data on Samian emery are collated and then examined with reference to the Naxian mineral. As far as the mineralogical structure of the Samos emery is concerned, besides the existing data, XRD mineralogical analysis, XRF/ICP major and trace element analysis and SEM-EDS micro-analysis was conducted, in order to recognize specific features of the Samos diasporite deposit. Finally, the few known archaeological findings that may indicate a probable ancient exploitation of the Samos emery are presented, underlining the need of further geological and archaeological research in the Aegean Region and Western Anatolia, in order to draw wider conclusions.

The Morava Mountain Oligocene-Middle Miocene molasse deposits take part in the Albanian-Thessalian Basin, which developed NW-SE from eastern Albania to Thessaly in Greece, where it is called as Mesohellenic Basin. The 4.5 km thick basin infill is subdivided into three molasse cycles separated by two regional unconformities at the Eocene/Oligocene and Aquitanian/Burdigalian boundaries. The Morava Mountain Oligocene-Middle Miocene molase, ~ 3500 m thick, represents an exposed continuous, rich in fossil fauna succession. Six stratigraphic sections were studied and measured.
