Abstract

Features that reflect parameters of the geological and tectonic structure in lithospheric magnetic anomalies obtained using measurements by the CHAMP Earth satellite. A database on full vector module T_a and vertical component Z_a of the lithosphere’s magnetic field at satellite altitudes is created using a original technology for separating an anomaly magnetic field from measurements made by the CHAMP satellite. The positions of large-scale anomalies over the territories of the eastern Carpathians, the Tarim large igneous province, the Khatanga trap plume and the Kolyma–Omolon microcontinent was determined. Data analysis on the magnetization of the lower crust structures in conjunction with other geophysical means allows us to identify conditions of the origin and evolution of the mantle and the mantle–crust ore-forming systems that result in the formation of large and unique ore deposits. It is shown that quantitative geological information can be derived from magnetic data by clarification of the boundaries position of Precambrian provinces covered by Phanerozoic sediments. As a parameter reflecting the actual positions of structures of the lower crust and their physical properties, the lithospheric magnetic field can be used to distinguish, contour and correct them in addition to other geological and geophysical means.

卫星地磁观测在岩石圈结构地质和构造研究中的可能用途

摘要

反映岩石圈磁异常中地质和构造结构参数的特征，该异常是通过使用CHAMP Earth卫星的测量获得的。上全矢量模块A数据库Ť_一个和垂直分量ž_一个使用原始技术创建了卫星高度的岩石圈磁场，以将异常磁场与CHAMP卫星的测量值分开。确定了喀尔巴阡山脉东部，塔里木大火成岩省，哈丹加trap陷羽状流和科利马-奥莫伦微大陆的大范围异常的位置。结合其他地球物理手段对下地壳结构的磁化进行数据分析，使我们能够确定地幔和地幔-成矿成矿系统的成因和演化条件，从而形成大量独特的矿床。结果表明，通过澄清古生代沉积物覆盖的前寒武纪省的边界位置，可以从磁数据中获得定量的地质信息。作为反映下地壳结构实际位置及其物理特性的参数，除了其他地质和地球物理手段外，岩石圈磁场还可用于区分，轮廓化和校正它们。
