甘肃迷坝矽卡岩型铜矿成矿机理及模式研究

Study on metallogenic mechanism and model of Miba Sicarn⁃typed copper deposit in Gansu Province

甘肃迷坝铜矿是近些年来在西秦岭发现的比较典型的矽卡岩型铜矿,本文研究了其区域地质背景、矿区地层、构造、岩浆岩及其矿体特征,分析了其成矿要素,总结了迷坝矽卡岩型铜矿成矿机理及模式,以期为西秦岭矽卡岩性的矿床的找矿提供参考。

The Miba copper deposit in Gansu Province is a typical skarn⁃type copper deposit discovered in west Qin Mountains in recent years.This paper studied its regional geological background,strata and structure of mine area,magmatic rocks,and ore⁃body features.The metallogenic elements,metallogenic mechanism and model of Miba skarn⁃type copper deposit were also summarized in order to provide a reference for the prospecting of West Qin Mountains Skarn⁃type copper deposit.
