浅析西秦岭金属矿床成矿地球化学特征

Analysis of Metallogenic Geochemical Characteristics of Metal Deposits in West Qinling

西秦岭地区大地构造位置独特,区内构造环境复杂,位于我国南北、东西地壳物理性质转换部位,造就了铜、铅、锌、金、铁、锰、钨、钼、锑、汞等矿产资源的广泛分布。本文介绍了西秦岭地区区域构造格架,分析了有利的控矿构造组合形式,总结了该区域主要矿产的赋矿地层及地层的地球化学特征,归纳了区内侵入岩的分布特征,进而分析了西秦岭地区铁、锰、铜、铅、锌、金矿的成矿地球化学特征。

The West Qinling region has a unique tectonic location, complex structure environment, located in China North and south, east and West crust physical properties of the transformation site, creating copper, lead, zinc, gold, iron, manganese, tungsten, molybdenum, antimony, mercury and other mineral resources widely distributed. In this paper, the regional tectonic framework in West Qinling area is introduced, and the advantageous ore-controlling structural combination forms are analyzed. This paper summarizes the geochemical characteristics of the ore-bearing strata and strata in the region, sums up the distribution characteristics of the intrusive rocks in the area, and then analyzes the metallogenic geochemical characteristics of Fe, MN, Cu, Pb, Zn and Au in the West Qinling region.
