从夏塞银矿发现与勘查谈川西义敦地区银矿找矿

夏塞银矿为四川西部重要的矿床类似之一。岩浆活动为夏塞银矿的形成提供了充分的矿源,断裂构造对矿体的产出控制明显,成矿元素及矿石组合分带清楚,具典型的热液型矿床特征。本文通过对夏塞银矿的成矿地质背景及控矿条件分析、类比,提出辛果隆巴等找矿靶区,并结合夏塞银矿的发现与勘查评价经验,对找矿靶区找矿思路、方法、手段等进行了探讨。

Study of Silver Mine Prospecting in Yidun Area of Western Sichuan from the Discovery and Exploration of the Xiasai Silver Mine

The Xiasai silver mine is one of the most important deposits of Western Sichuan. Magmatic activities provide adequate source for the formation of the Xiasai silver, and the output of the ore is obviously under the control of faulted structure. The ore-formingelements and minerals combination have clear zones, which is with typical characteristics of hydrothermal ore deposits. Based on the analysis and analogy of ore-forming geological background and ore-controlling conditions of Xiasai silver, Xinguolongba is proposed to bethe prospecting target zone, and combining the experience of the discovery, exploration and evaluation of the Xiasai silver, the way, means and methods of prospecting ore argets are discussed.
