| 摘 要： | 吉林省中南部产出系列铜镍硫化物矿床,形成于中生代早期的含矿镁铁-超镁铁质岩体在含矿岩体空间上受断裂构造控制,并且在一定范围内集中出现,构成具有成因联系的含矿岩体群。三道岗含矿岩体主要岩石类型为闪长岩、辉长岩、角闪辉石岩-辉石岩、含长角闪橄榄岩等组合,侵位于下二叠统范家屯组浅变质岩系中。辉长岩中LA-ICP-MS锆石原位定年得到(232.75±0.95)Ma(MSWD=0.87)的岩体结晶年龄,同时,角闪石单矿物40Ar-39Ar法测年得到(121.45±2.52)Ma的蚀变年龄,暗示三道岗含矿岩体群与红旗岭一样形成于印支中亚造山晚期,燕山期岩浆活动产生的热液叠加蚀变对矿床形成产生重要影响。

| Abstract: | A series of Cu-Ni sulfide deposits was discovered in south-central Jilin Province and some of the ore-bearing mafic-ultramafic intrusions were formed in the Early Mesozoic.Controlled by faults and concentrated in a certain area,the ore-bearing intrusions make up a few genetically related intrusion clusters.These ore-bearing intrusions,include diorite,gabbro,hornblende pyroxenite-pyroxenite and feldspathic hornblende-peridotite,etc,were intruded into the metamorphic rocks of the Fanjiatun Formation of the Lo... |
