在前人工作的基础上,作者用Rb—Sr法测定了红透山一树基沟变质铜矿床地区一些伟晶岩、变质岩的全岩和单矿物样品,得到了老于28亿年的Rb—Sr年龄值.并采用全岩等时线和全岩—单矿物内部等时线法测定了红透山绿长石花岗伟晶岩和树基沟花岗质混合岩树54全岩及从中选出的单矿物黑云母和角闪石的Rb—St年龄.结合有关资料讨论了该地区的区域变质作用,铜矿的多次成矿,Rb—Sr跟K—Ar年龄的一致与不一致的某些原因、鞍山群的时代以及红透山一树基沟铜矿带成岩成矿的物质来源问题.
Based on the previous work, the author measured the whole rock and single mineral samples of some pegmatites and metamorphic rocks in the Hongtoushan-Shushengou metamorphic copper deposit area by Rb-Sr method, The Rb-Sr ages of the Hongtoushan feldspathic granitic pegmatites and the Shuguigou granitic mixed rock 54 were measured by using the whole-rock isochron and the whole rock-single mineral internal isochronism method And the Rb-St age of single-mineral biotite and amphibole from which they were selected.Combined with the relevant data, the regional metamorphism of the area, the multiple mineralization of copper mines, the coincidence of Rb-Sr with K-Ar age and Some reasons of inconsistency, the age of Anshan Group, and the material source of diagenesis and mineralization of the Hongtoushan-Shuguigou copper belt.
