摘要
伊昆古金矿床产于中太古界尼安兹群绿岩带内,晚太古代岩浆活动形成了含金石英脉型中低温热液矿床。通过土壤与岩石地球化学测量,基本查明了金矿化特征、金矿化与砷(As)异常的关系;结合地层、岩性与矿化特征及区域成矿模式进行成因分析,确定找矿方向。
Yikun ancient gold deposit occurred in greenstone belt of Mesoarchean Erathem.Through geochemical survey of soil and rock,the paper basically identified gold mineralization characteristics,abnormal relationship between gold mineraliztion and arsenic.Combined with stratigraphy,lithology,mineralization characteristics and regional metallogenic model,the paper analyzed genesis,determine prospecting direction.
