This article discusses a comprehensive study of the sand samples, which were selected on the Arabian seashores (Kovalam, Kollam, Kerala, India), and produced ilmenite, zircon, garnet and monazite concentrates (Chavara field, Kerala, India). As a result of versatile research, realized in the laboratories of KFU, which represented mineral and radionuclide composition of the studied samples, marginally represented La, Yb, Hf. Discovered free of impurities zircon, as well as zircon of the hafnium species. The studies ...

The development of oil deposits in the Republic of Tatarstan is entering a late stage. Deposits of natural bitumen of Cheremshano-Yamashinskaya structural zone, in particular, Ashalchinskoye, Mordovo-Karmalskoye and others, were studied. For their development requires the use of active methods пїЅ method of thermal (steam-thermal) impact. The use of method is limited by the stability conditions of its fluid seals. Fluid seals are the layers of пїЅlingul clayпїЅ пїЅ deposits of the Kazanian stage. They are represen...

Seals of oil deposits of Tatarstan (Volga-Ural petroleum province) are a complex geological and geochemical object. The preservation degree of hydrocarbon deposits is determined by the filtration characteristics of the seals. Migration of the identified portions of hydrocarbon compounds through the fluid lead to a violation of lithological-geochemical equilibrium in the seal. The development of pyrite in the seals is connected both with the syndiagenetic processes of sediment transformation and with biomineralogic...

Within the crystalline basement of the Tatar arch of the East-Russian plate, specific zones are distinguished, which can be attributed to unconventional reservoir zones. According to previous studies, different types of genesis are generated: decompressed zones of destruction of great depths, weathering crusts at the boundary of the sedimentary cover and crystalline basement, fractured permeable zones subjected to later hydrothermal processes, etc. Formation of different types of reservoir zones is associated with...
