竹园沟钨钼矿床地质特征及找矿远景分析

Geological characteristics and ore-searching prospects of the Zhuyuangou tungsten-molybdenum ore deposit

竹园沟钨钼矿是近年来在东秦岭地区发现的又一大型钨钼矿。在讨论成矿地质背景基础上,对矿床地质特征进行了研究。矿体的空间分布与矿区内褶皱、断裂、岩性、围岩热液蚀变强度有关,矿体受黄背岭背斜及石宝沟斑状二长花岗岩侵入体向北西侧伏的内外接触带控制。矿床成因为斑岩-矽卡岩型钼矿床。同时指出了找矿标志,分析了找矿远景,对以后的找矿工作有一定的指导意义。

The in East Qinling Zhuyuangou ore deposit is a large-sized tungsten-molybdenum deposit discovered in recent years area. Its geological features were studied in this paper on the basis of the geological background. The distribution of ore bodies is related to folds, fractures, lithology and intensity of wall-rock hydrothermal alteration in the ore district, and the ore bodies are controlled by the Huangbeiling anticline and the endo- exocontact zones of the northwest-pitching Shibaogou porphyritic adameUite intrusive. The ore deposit is genetically of the porphyry-skarn type. Ore-searching criteria and prospects are indicated in this paper, which are of some significance for further ore-searching work.
