上冯铜钼矿区金沙岭矿段找矿信息标志

Prospecting Indicators of the Jinshaling Ore Block of Shangfeng Cu-Mo Ore Deposit

上冯矿区铜钼矿(化)体产于燕山晚期黑云母花岗闪长岩及其与上侏罗统高坞组流纹质晶屑玻屑凝灰岩的接触带(角岩化带)。区域成矿地质背景得天独厚,岩浆活动频繁,为矿区铜钼矿的富集成矿提供了有利条件。在对区内成矿地质条件、1∶1万土壤地球化学特征、地球物理特征进行分析的基础上,分别从地质因素、地球化学、地球物理等方面对上冯矿区金沙岭矿段的综合信息找矿标志进行了探讨,为该矿区深部及外围找矿工作提供参考。

Shangfeng Cu-Mo deposit is located in the contact zones （hornfelsic zones） between Late Yanshanian granodiorites and Upper Jurassic Gaowu formation rhyolitic crystal-vitric tuff. The deposit possesses favorable metallogenic background and the active magnetic activity provide good conditions for Shangfeng copper-molybdenum mineralization. Based on analyzing the ore-forming geological conditions, 1：10 000 soil geochemical characteristics, geophysical characteristics, the prospecting indicators of the Jinshaling ore block of Shangfeng Cu-Mo deposit are discussed from the perspective of geological factors, geochemical and geophysical so as to provide some reference for the deep and periphery prospecting work in the mining area.
