东川落因矿区小溜口火山杂岩金铜矿化特征研究

Study on Ag-Cu mineralization characteristics of Xiaoliukou volcanic complex rock in Luoyin mining area,Dongchuan

落因地区小溜口火山杂岩由于火山喷发中心的差异及断裂构造和岩浆多期活动,其岩石组合混杂,相互关系复杂,多年以来对其研究程度不高,并忽视该火山杂岩的找矿工作。经过笔者近年来的地质工作,对火山杂岩的成矿特征及规律有了新的认识,找矿取得了新的进展和突破。

As a result of the difference between various volcano eruption centers and multiperiodic activity of faulted structure and magma,Xiaoliukou volcanic complex rock in Luoyin area has confounding rock assemblages and complicated interrelationships between them,therefore the researchers had little interest in it over the years and prospecting in the volcanic complex rocks has being neglected.Based on the former works in recent years,the authors gain the new understanding in the characteristics and regularity of mineralization in volcanic complex rocks,and new development and breakthrough has been achieved in the prospecting works.
