昆明东川区播卡金矿地球化学特征与成因

摘要

播卡金矿位于云南的东川区,由16条矿体组成.在搜集以往地质、化探资料的基础上,结合野外实地调研,研究了播卡矿区地层、岩浆岩、矿石的微量元素地球化学特征,从地球化学的角度探讨了播卡矿床的成因,依据稀土元素的分析结果研究了播卡矿床的成矿物质来源,在此基础上分析了播卡金矿的成矿过程及成矿机制.%Located in Dongchuan of Yunnan Province, the Boka gold deposit contains 16 ore bodies.This research was based on geological and geochemical data in combination with field work.The authors studied geochemical characteristics of trace elements in strata, magmatic rocks and ores, and discussed the genesis of the Boka ore deposit from the angle of geochemistry.Based on an analysis of rare earth elements, the authors deduced the sources of ore minerals, and analyzed the ore-forming process and mechanism of the Boka gold deposit.
