福建建宁椒坑—金坑一带金矿成矿地质特征及成矿预测

On the Geological Characteristics and Metallogenic Prediction of Gold Deposit of Jiaokeng-Jinkeng Area in Jianning County,Fujian Province

以前人工作成果为基础,通过研究区成矿地质特征及成矿相关信息分析,论述区内金矿的成矿规律和找矿标志,认为矿床受北东向与近东西向的脆性断裂构造控制,矿床成因类型属构造蚀变岩型金矿床。运用成矿规律和地质、重砂、地球化学特征综合类比进行成矿预测,共圈定两个成矿预测区。

The article based on predecessors＂ working ahievement, and analysising the ore-forming geological characteristics and metallogenic information , discussing the metallogenic regularity and prospecting marks of gold deposits in the area , come to a conclusion that the deposits are controlled by the brittle fracture tectonic of the northeast and near east-west, deposit genetic type belongs to structural altered rock type gold deposit. Application of the theory of metallogenic regularities and the natural heavy mineral, geochemical characteristics of the integrated analog metallogenic prediction, delineats two metallogenic prediction area.
