湖南铜山岭矿区地质特征及边部找矿前景分析

Geological characteristics and prospecting potential of Tongshanling mining area in Hunan

在综合研究区域地质背景、矿区地质特征的基础上,结合最近开展边部勘查工作取得成果,总结找矿经验。分析铜山岭边部地区隐伏花岗闪长岩体顶板变化形态与成矿关系,矿床地质特征,岩(矿)石特征,围岩蚀变特征;总结岩体接触带矽卡岩型铜铅锌银钨多金属矿体成矿规律以及重要矿种分布规律;进行边部地区找矿前景分析,提出找矿主攻矿种及方向,预测了一个钨钼铋矿种找矿靶区和一个铜铅锌银矿种找矿靶区,为下一步找矿提供指导。

This paper is to summarize prospecting experience based on a comprehensive study of the regional geological background and geological features of the mining area and combing with the results of the recent exploration at the outer of the mining area. Morphological changes and mineralization relationship of the roof of blind granodiorite mass, the geological characteristics of ore deposits, the characteristics of rocks and alteration at the outer area of Tongshanling shall be analyzed;metallogenic law of copper-lead-zinc-silver-tungsten polymetallic ore body of skarn-type at the contact zone of the body and distribution law of important minerals shall be summarized;an analysis shall be made on the prospecting prospect of the outer area and major prospecting minerals and direction shall be put forward;one prospecting target area of tungsten-molybdenum- bismuth minerals and another one of copper-lead- zinc- silver minerals are predicted, providing guidance for the following prospecting.
