前言近年来,我们在本区进行与火成活动有关的以铁、铜、铬为主的区域成矿地质特征的课题研究工作,有机会对超基性岩进行了调查研究。为了“互通情报”,交流经验,故将所获资料初步总结写成此文。文中所用资料,除本组调查所得外,还参考了青海省地质局区域地质测量队、第四、十三地质队等单位的地质成果和我所兄弟组在上庄磷灰石矿区研究的资料。同时,工作中得到了
Preface In recent years, we have carried out research work on regional geological characteristics of iron ore, copper and chromium related to igneous activities in this area and have the opportunity to conduct investigations and studies on ultrabasic rocks. In order to “exchange information” and exchange experiences, the preliminary summary of the information obtained was written as this article. The data used in this article, in addition to the survey results of this group, also refer to the geological achievements of the Geological Survey of Qinghai Province’s Geological Bureau, the geological units of the fourth and the thirteenth, and the data of the research conducted by our brothers in the Shangzhuang apatite mine.
