The Vanavar Formation is a terrigenous horizon (1 to 200 m thick) at the boundary of the Tonian-Cryogenian and Ediacaran-Fortunian carbonate complexes. The geological position of the Vanavar Formation and the intensive facies variability do not permit a clear characterization of the conditions for its accumulation. Additional interest in the study of Vanavar Formation caused by its oil-and-gas bearing deposits. The objects of research are the core samples selected from well ? 3 of Pridutsky area. The mineral and c...

In terms of development of agriculture, industry and tourism, in the spatial planning the level of exploration of mineral resources and environmental protection in rural areas is of great importance. The area of Vranje tertiary basin, located in the western part of the Serbian-Macedonian massif was selected. It spreads on both sides of the South Morava river, from Vladicin Han at the North, via Vranje and Ristovac to Bujanovac at the South. The total length of the basin is about 30 km and the width varies from 10 ...

The paper presents geochemical researches of the Westphalian sedimentary rocks from the Lublin Coal Basin (Poland) with the use of various digestion methods.For all samples the concentration of main and trace elements was identified (Co, Mn, Bi, Cu, Zn, Mo, Pb, Ni, Fe, P, Mg, U, Ca, Sr, Zr, K, Rb, Al, V, Ba, Cr, Na, Th, Cd), using inductively coupled plasma mass spectroscopy (ICP-MS) The samples were prepared for testing by means of two different dissolution methods: the method of complete dissolution ? multi-acid...

This study focuses on the source potential distribution within the Menilite Beds (Oligocene) in the Central Carpathian Synclinorium (Silesian Nappe) in the eastern part of the Polish Outer Carpathians. This region of the Polish Carpathians is one of the oldest petroleum-producing regions in the world, where in several folds plenty of oil and gas fields were discovered. The Menilite series contain the best source rocks in the Carpathians: the Menilite Shales, in which the liptynite group with humic components is a ...

Establishment of regular river sediment monitoring, in addition to water monitoring, is very important, as geochemical data of sediments are very significant for environmental impact assessment. First scientific investigations of sediments in Croatia started in the Krka River estuary in 1989, while first systematic research of a river basin in Croatia was performed in the Kupa River drainage basin in 2005. In 2008, Croatian water authorities (Hrvatske Vode) started a preliminary sediment monitoring program. Since ...

The Sakarya zone in Anatolia is a continental fragment >1500 km long and 120 km wide. This continent is divided into three zones: western, central and eastern. This volcanism is related to western Anatolia orogenic belt around Sakarya zone which produced Late Eocene-Late Miocene-aged mainly acidic and intermediate volcanic rocks. They are mainly composed of andesite, dacite, and latite lavas with associated pyroclastic rocks. The central Sakarya zone volcanic unit is mainly composed of Eocene-aged andesite and dac...

Plutonic rocks are quite widespread throughout Anatolia (Turkey) ranging from gabbro to granite and calc-alkaline to alkaline. One of those rocks are located in Kahramanmaras, SE of Anatolia, and named as the Buyukkizilcik intrusive rocks. This area is situated in one of continental blocks of Anatolia, Tauride Belt. The basement of the studied area is composed of Paleozoic-Mesozoic metamorphic rocks and they are cut by the intrusive rocks. In the field these rocks are quite altered. These intrusive rocks are alkal...
