摘要
地球化学异常的有序排列应用于找矿方面的成效是显著的,可用以推断矿体剥蚀程度、评价矿体埋深、寻找盲矿。本文从另一侧面探讨区域地球化学异常的有序排列在基础地质研究中的应用:归纳了识别断裂构造的区域地球化学标志,辨认环状构造,圈定岩体边界,推测隐伏、半隐伏岩体的做法。并对该应用领域作了展望,如据此追索矿源层,为大地构造单元的分界提供佐证,为板块构造、推覆构造及地体划分寻找依据等等。
The application of orderly arrangement of geochemical anomalies to mineral prospecting has achieved remarkable results on the inference of orebody erosion, the evaluation of orebody depth, and the discovery of blind orebody. The paper is trying to discuss the application of orderly arrangement of geoehernieal anomalies to fundamental geological research from another aspect. It sums up the methods to identify regional geochemical evidences of fault structure, to discriminate ring structure, to define rock body, and to infer concealed or semi-concealed rock mass. Besides, a future look onto the applica tion has been taken, such as tracing source-bed, providing evidences of geotectonic boundary, and look ing for evidences to divide plate tectonics, nappe structures as well as terranes etc..
