福建南靖南坑钼多金属矿异常特征及找矿远景分析

南靖南坑土壤地球化学圈出5个Mo多金属综合异常,异常呈北东向分布在燕山早期中酸性侵入岩与文宾山组碎屑岩接触带及断裂带附近,异常元素组合以Cu、Mo为主,伴有Pb、Zn、W等,浓集中心明显,局部证实为矿致异常,其中甲3-1异常经详查,Mo多金属矿达中型规模,综合分析该区成矿地质背景、地球化学特征和已发现矿(化)点,认为南坑一带具有良好的钼矿找矿远景。

On the anomaly characteristics and Ore-finding Perspective of the Nankeng molybdenum Polymetallic Deposit in Nanjing County, Fujian Pro.

In nankeng deposit of Nanjing County, five Mo polymetallic synthetical abnormalies of soil geochemisty are east-north distributed near fractured and contact belt between Yanshan early intermediate acidic instrusive rocks and Binshan clastic rocks. Cu and Mo are major anomalous element combination with Pb. Zn. W and the contraction center of the anomalies is obvious, which local confirmed ore-induced anomaly. With using detailed survey A3-1 anomaly, molybdenum polymetallic deposit is mid-scale. Based on the multipurpose analysis of metallogenic geological background, geochemical characteristics and found mineralized points, it is considered that the surveyed area is one of the better metallogenic perspective areas of hunting for the molybdenum deposits.
