前孙家—洼孙家断裂南段岩石微量元素和稀土元素特征

摘要

通过对前孙家矿区和金华山矿区岩石微量元素与稀土元素地球化学的研究,认为两矿区重稀土元素与成矿关系密切,绢英岩化蚀变晚于钾化蚀变,与金元素相关的亲硫元素是蚀变活化过程中带入的元素.研究成果对追溯本区域成矿物质来源及进一步找矿具有指导意义.%Based on the study about geochemical characteristics of REE and trace elements of Qiansunjia-Jinhuashan gold mining area,the article thinks that HREE closely related to mineralization in the two mining area,phyllic alteration is later than potassic alteration,sulphophile elements related Au elements are activate and brought during the alteration process,it has guiding significance for retrospectiving the source of ore and a further prospecting in this region.
