康古尔金矿地球化学分带模式及其预测标志

GEOCHEMICAL ZONATION MODEL AND PREDICTION MARKS OF KANGUER GOLD DEPOSIT

康古尔金矿受火山运动及韧性剪切作用双重控制;成矿母岩为中—酸性火山岩;矿化与黄铁绢英岩化、绿泥石化、硅化关系密切;指示元素组合类型,主要成矿元素Au和多金属为选择分布的两期成矿产物;矿床地球化学分带明显,但主要成矿元素相关性不明显,所建立的矿床剥蚀深度数学模式,对于矿脉勘探评价和寻找深部肓矿体具有一定的指导意义。

The Kanguer gold deposit is controlled by volcanic activities and ductile shearing. Its mother rocks are intermediate-acid volcanics. The mineralization has a close relation with beresitization,chloritization and silicification. The indicative elements (association type) and the main ore-forming elements (Au and multi-metals) are the product of two different metallogenic stages. The geochemical zonation of the deposit is obvious,but that of the main ore-forming elements is not. A mathematic model of erosion depth is set up, which is significant to a certain extent on the prospecting and evaluation of ore veins and in the searching of deep blind ore bodies.
