某矿区经过几年的铜、镍次生晕工作,虽取得了大量资料及一些地质效果,但有些问题仍未完全解决,例如:许多基性-超基性岩体地表浸有铜、镍次生晕的原因,合理的工作方法,以及铜、镍次生晕在本区所能起的作用.我们针对这些问题在63年进行了初步研究.矿区位于稳定的地台和活动的准褶皱带交界处,基性-超基性岩体受二者之间的深大断裂的次一级断裂系统控制,侵入于前震旦系片麻岩中.岩体一般从超基性岩到基性岩相,分異良好.矿体赋存在超基性
After several years of copper and nickel dimming work in a certain mining area, a great deal of data and some geological effects have been obtained, but some problems have not yet been fully solved. For example, the surface of many basic-ultrabasic rocks is impregnated with copper and nickel The causes of dizziness, rational working methods, and the role that copper and nickel secondary halo can play in this area.We conducted a preliminary study on these problems in 63. The mine is located on a stable platform and active quasi-fold belt At the junction, the basic-ultramafic rocks are controlled by the deep-fault secondary fault system between the two and intrude into the former Sinian gneisses, generally from ultrabasic rocks to basic rocks Phase, good differentiation. Ore body exists in the ultrabasic
