Abstract

Analysis of the latest seismic data has shown that thick sedimentary basins are developed in the western part of the Laptev Sea and on the continental margin of the Siberian Platform. They are separated by a large basement high, the presence of which makes it difficult to compare sedimentary complexes on the continent and in a water area. An integrated analysis of geological and geophysical data on the continental margin of the Siberian Platform, the Laptev Sea, and adjacent folded structures was carried out. Furthermore, seismogeological models of sedimentary complexes on the continent and in a water area were constructed and correlated, potential fields were analyzed, and a structural map of the top of the crystalline basement was constructed. A comparative analysis of the geological and geophysical materials showed that the western part of the Laptev Sea is a northern continuation of the Siberian Platform and the oil and gas potential of this part of the sea will be associated mainly with the Upper Proterozoic–Paleozoic deposits.

西伯利亚台地和拉普捷夫海架北极地区的地质剖面地震地质特征和分层

摘要

对最新地震数据的分析表明，在拉普捷夫海的西部和西伯利亚台地的大陆边缘发育了厚厚的沉积盆地。它们被高大的地下室分隔开，由于地下室的存在，很难比较大陆和水域的沉积物。对西伯利亚平台大陆边缘，拉普捷夫海及邻近折叠构造的地质和地球物理数据进行了综合分析。此外，建立并关联了大陆和水域沉积复合物的地震地质模型，分析了势场，并建立了结晶基底顶部的结构图。
