Miocene foraminifer complexes of Karaginsky Island,East Kamchatka     

S. I. Bordunov 《Moscow University Geology Bulletin》2008,63(6):372-378

Investigation of Miocene foraminifers in Karaginsky Island allowed recognition of 13 complexes. In all, three complexes were recognized in the Variegated Formation, eight complexes were found in the Plosky Cape Formation, and three were recorded in the Yunyun’vayam Creak Formation. The changes in their nature were related to changes in paleoenvironments. The composition of complexes indicates their accumulation under conditions of the outer shelf and continental slope. The recognized foraminifer complexes allow correlating successions in Karaginsky Island with Lower-Upper Miocene successions of the Northern Pacific.  相似文献   

The oil and gas potential of the Kuma rocks of the Bakhchisarai region of Crimea

The oil and gas potential of the Kuma Formation of the Bakhchisarai region (southwestern Crimea) was substantiated on the basis of a lithological and micropaleontological study of the rocks of the section of the formation and geochemical (luminescent-bituminous, gas-liquid chromatographic, pyrolytic, and isotope) studies of the organic matter of the rocks. New regions for study that are favorable for the origination of the oil system in this formation were identified.  相似文献   

The tectonics and stages of the geological history of the Yenisei–Khatanga Basin and the conjugate Taimyr Orogen

A new interpretation of the seismic profile series for the Taimyr Orogen and the Yenisei–Khatanga Basin is given in terms of their tectonics and geological history. The tectonics and tectonostratigraphy of the Yenisei–Khatanga and the Khatanga–Lena basins are considered. In the Late Vendian and Early Paleozoic, a passive continental margin and postrift shelf basin existed in Taimyr and the Yenisei–Khatanga Basin. From the Early Carboniferous to the Mid-Permian, the North and Central Taimyr zones were involved in orogeny. The Late Paleozoic foredeep was formed in the contemporary South Taimyr Zone. In the Middle to Late Triassic, a new orogeny took place in the large territory of Taimyr and the Noril’sk district of the Siberian Platform. A synorogenic foredeep has been recognized for the first time close to the Yenisei–Khatanga Basin. In the Jurassic and Early Cretaceous, this basin was subsided under transpressional conditions. Thereby, anticlinal swells were formed from the Callovian to the Aptian. Their growth continued in the Cenozoic. The Taimyr Orogen underwent tectonic reactivation and apparently right-lateral transpression from Carboniferous to Cenozoic.  相似文献   

The source rocks in the southwestern part of the South Sakhalin Basin

In the southwestern part of the South Sakhalin Basin, the main source rocks are early Miocene clayey deposits of the Upper Due Suite, middle Miocene dark gray and black mudstone of the Kurasiy Suite, and, probably, black mudstone of the Bykov Suite of Late Cretaceous age.  相似文献
