南巴伦支海磁场异常及其与海底地质结构的对比(英文)

Southern Barents Sea anomalous magnetic field and its correlation with bottom geological structure

对1986—2001年间巴伦支海南部海洋磁力测量的数据处理结果进行了研究。南巴伦支海底的地磁测量揭示出其复杂多期的地质构造结构,其中以两期分离型的构造为主导:(1)具NW走向的里菲-文德期继承性裂谷构造;(2)NE向转换叠加断层正交系统。晚泥盆世碱性侵入体及其相关的金属矿化作用恰位于这些构造系统的交点上。

Results of data processing of marine magnetic surveys in a southern part of Barents Sea,executed from 1986 to 2001 are considered.The geomagnetic investigation of Southern Barents Sea bottom points on its complicated many-stage geologic-tectonic structures in which two disjunctive structures prevail：Riphean-Vendian inherited rift structures with north-west strike and orthogonal system of superposed faults transformed in north-eastern direction.Late Devonian alkaline intrusives with associated ore mineralization are confined to points of these systems intersection.
