甘肃省西秦岭柴家庄- 太阳寺一带金铅锌矿成矿条件及潜力分析

Analysis of ore-forming conditions and potential of gold lead zinc deposits in the Chaijiazhuang Taiyangsi area of the western Qinling Mountains in Gansu Province

研究区以往地质工作程度较高,区内铜矿(化)点遍布;从地质特征分析认为该区成矿潜力良好,有形成金铅锌矿多金属矿的有利条件;多期构造及岩浆岩活动,为热液型内生矿产形成,可提供优越的条件,区内已发现金、铅、锌、银、铜、汞、锑、铁等矿床(点)百余处,矿床(点)产于早古生代丹凤群、泥盆纪舒家坝组中,以热液型为主,并受韧、脆性断裂构造控制。本次研究工作针对该区金铅锌矿多金属矿等的成矿条件进行分析,进一步总结了金铅锌矿多金属矿在该地区的成矿潜力。

The previous geological work in the research area was relatively high,with copper(mineralization)points scattered throughout the area;From the analysis of geological characteristics,it is believed that the mineralization potential in this area is good and there are favorable conditions for the formation of gold lead zinc polymetallic deposits;Multiple periods of tectonic and magmatic activity provide favorable conditions for the formation of hydrothermal endogenous minerals.Over a hundred deposits(points)of cash,lead,zinc,silver,copper,mercury,antimony,iron,etc.have been discovered in the area.These deposits(points)occur in the early Paleozoic Danfeng Group and the Devonian Shujiaba Formation,mainly of hydrothermal type,and are controlled by ductile and brittle fault structures.This research work analyzes the ore-forming conditions of the gold lead zinc polymetallic deposits in the region,and further summarizes the ore-forming potential of the gold lead zinc polymetallic deposits in the region.
