摘要
同样赋存于老岭地区早元古代黑色岩系的大横路、杉松岗两Co-Cu矿床基础地质特征基本一致。用ICP-MS测定了两矿床共六件样品的微量元素及PGE元素。与前人统计资料的对比认为,PGE元素的地外物质来源可能性不大,Au-PGE的异常富集是海底热卤水与正常海水共同作用的结果。两矿床属于海底喷流加后期叠加改造的成因模式。
The geochemical characteristics of platinum group elements ＆ Genesis about The deposit of Cu-Co-Ni which have the relation of black rock series of Paleo- proterozoic, laoling area ofjilin province. The contents of platinum group elements （PGE） and Trace Element of six patterns in two deposits were determined using ICP-MS analysis, and high richments of Au-PGE might result from mixing of hot bittern seawater sediments and normal seawater sediements , instead of the platinum elements coming from exo-terrestrial materials. Solutions. two deposits has genesis of submarine exhalative deposition ,sueperimposed by late thermal solutions.
