ИЗОТОПНАЯ ГЕОЛОГИЯ ДРЕВНЕЙШИХ ОБРАЗОВАНИЙ ЮЖНОГО УРАЛА

Литосфера (2012)

The oldest Taratash and Aleksandrov polymetamorphic complexes of the Southern Urals were studied by structural, petrological and modern methods of isotope geology. These complexes are unique objects which the early history of the basement of the Urals and the eastern margin of the East European Craton was recorded in. Obtained U-Pb, Sm-Nd, Rb-Sr and 40Ar-39Ar isotope data for various rocks and minerals from the Taratash and Aleksandrov complexes fix age of some events in a range 3504 ± 210 ÷ 299 ± 4 Ma in depending on stability of concrete isotope system from temperature, pressure and fluid conditions.

Микроэлементы в нефтях некоторых месторождений-сателлитов Ромашкинского нефтяного поля (Республика Татарстан)

The article describes the results of studies of crude oils microelements composition in Chekan, Tumutuk and Tumutuk-Chekan satellite deposits of Romashkinskoye oil field. It was found that mentioned deposits belong to the group enriched in microelements. Median content of trace element in different producing horizons differ markedly. Investigated crude oils are characterized by very high V/Cu and V/Pb, which may indicate a slight manifestation of catagenetic changes. However such conclusion contraries to the rather low values of V/Fe which imply a significant elaborateness of naphthides. Median values of Ni/Cu (from 146 to ~330) suggest the absence of significant migration of naphthides as well as a sufficiently low level of their catagenetic transformations. It was established that on the diagram Gd N /Yb N -Eu/Eu* majority of data points of crude oil are localized in the field typical of fine-grained clastic formations, in which a significant or dominant role belongs to the products of erosion of primitive Archean substrates. The median value of Pt/Pd in the whole oils of Romashkinskoye field is ~60. Crude oils of Chekan, Tumutuk and Tumutuk-Chekan deposits according to the ratio of platinum group elements belong to the ruthenium-rhodium type.
