摘要
地质异常是一种与周围地质环境截然不同的地质结构。研究并查明何种地质异常导致成矿,上指导找矿和勘探工作的有效手段。文中以新疆北山地区成矿预测为刨,说明地质异常的应用敢果。该区的区域地质异常主要形成在晚古生代阶段。异常空间分布区——华力西期铜镍矿基性—超基性杂岩体。 研究地质异常演化规律对揭示成矿机理,查明和圈定物、化探异常更具实际意义。
Geologic anomaly is a geologic structure utterly different from that of surrounding geologic enviroments. It is very effective in prospecting to study and find out what kind of geologic anomaly causes the formation of ore deposits. The Baishan area of Xinjiang is taken as an example in this paper to show the application of geologic anomaly in the metallogenic prognosis. The regional geologic anomaly in this area was mainly formed during late Paleozoic time, and distributed in the Variscan basic-ultrabasic complexes. The study of evolution regularity of anomaly has a more practical significance in revealing metallogenic mechanism, examining and confining the geophysical and geochemical anomalies.
