红旗岭一带中生代铜镍成矿能力及主导因素

介绍了红旗岭一带中生代铜镍成矿能力及主导因素,指出该区域中生代铜镍成矿能力极弱,印支期幔源铜镍成矿作用褪,燕山期幔源铜镍成矿微弱。红旗岭一带印支期镍成矿消褪,厚地壳、厚岩石圈条件及强挤压应力背景是主导因素,而燕山期镍不成矿,镍挣脱地心引力的能力弱是主导因素。

Mesozoic Copper and Nickle Mineralization Capability and Leading Factor in Hongqiling Area

The paper introduces the Mesozoic copper and nickle mineralization capability and leading factor in Hongqiling area,pointing out that the Mesozoic copper and nickle mineralization capability is very weak in this area. Mantle source copper and nickle mineralization in the Indo-China period is disappearing;mantle source copper and nickle in the Yanshan period mineralization is weak;nickle mineralization in Indo-China period is disappearing in Hongqiling Area. The Leading factors are the situations of thick earthcrust and thick lithosphere and strong crushing stress. However,the leading factors are the non-mineralization of nickle in Yanshan period and weak ability of nickle breaking through the earth gravity.
