Abstract

The article considers maps of the field of lithospheric magnetic anomalies—images of the deep structures of the Arctic Ocean—constructed from observations by the CHAMP satellite. The lithospheric magnetic anomalies corresponding to the most significant tectonic structures were revealed: Lomonosov Ridge, Mendeleev Ridge, Alpha Rise, and the Amundsen, Podvodnikov and Makarov basins. The distribution of the regional magnetic anomaly field, which is a complex set of positive and negative segments of various shapes and amplitudes, is discussed in light of the modern geological and geophysical views on the structure of the Arctic Ocean lithosphere. The constructed lithospheric magnetic field model indicates that in the region of conjugation with Eurasia the foot and the slope of Lomonosov Ridge are morphologically related to the continental margin, while the area of Mendeleev and Alpha elevations in central Arctic appears to be a single-block structure with a continental-type crust.

岩石圈磁场对北冰洋东部大型构造结构的反射

摘要

本文考虑了由CHAMP卫星的观测结果构成的岩石圈磁异常场的地图（北冰洋深层结构的图像）。揭示了与最重要的构造结构相对应的岩石圈磁异常：罗蒙诺索夫岭，门捷列夫岭，阿尔法崛起以及阿蒙森，波德沃尼科夫盆地和马卡洛夫盆地。根据北冰洋岩石圈结构的现代地质和地球物理观点，对区域磁场异常场的分布进行了讨论，该区域磁场是由各种形状和振幅组成的正负片段的复杂集合。建立的岩石圈磁场模型表明，在与欧亚大陆共轭的区域中，罗蒙诺索夫山脊的脚和坡度在形态上与大陆边缘有关，
