2D and 3D geotemperature models of the sedimentary cover within the Laptev Sea shelf have been calculated. The presence of
several “thermal domes” (zones of uplifted isotherms) has been found. Based on analogous sedimentary basins with domes, which
correlate to the location of hydrocarbon deposits, the forecasting has been made that the Ust-Lena graben and Omoloi trough
are the most promising areas for oil-and-gas prospecting. 相似文献

2D and 3D modeling of the geothermal field was carried out along seven extended geotraverses in the Barents Sea compiled on the basis of CMP profiling and results of deep drilling. Depths of the zone characterized by catagenetic transformation of organic matter were calculated for different areas of the sedimentary basin. The minimal depth is confined to the South Barents Basin with the highest hydrocarbon resource potential established by geological exploration. In 3D models, this area is distinguished by a thermal dome recognized for the first time. 相似文献

A representative collection (138 analyses) of chromites from kimberlites of the Botuobinskaya pipe in Yakutia was studied.
With allowance for the Cr, Ti, and Al contents, the chromites are subdivided into the low-Cr aluminous group A and the high-Cr
and high-Ti group B. The chromites of group A with their compositional variations controlled by the Al3+-Cr3+ isomorphism are not related to kimberlite in composition and reveal attributes of restites. The chromites of group B with
heterovalent Ti4+ + Fe2+ + Fe3+-3Cr3+ isomorphism vary in their composition in line with the compositional variations of kimberlites, thus demonstrating their
primary magmatic origin. The chromites of the second group crystallized simultaneously with olivines from kimberlites, and
both minerals could have formed nodules of spinel dunite. 相似文献
