青海省茫崖河东地区铁多金属矿成矿模式研究

Study on metallogenic model of iron polymetallic deposits in the Mangya River east area in Qinghai Province

青海省茫崖河东地区在青海省祁漫塔格成矿远景区内,区内构造、岩脉发育,控制了该区矿体的形成、展布。区内地质情况复杂,通过大量实地地质工作,并结合地质成果资料,在分析研究区所处大地构造位置、区域地质背景、矽卡岩带特征、矿体特征的基础上,总结分析了该区的控矿因素和找矿标志,初步建立了成矿模式图,对该区域铁矿体及铅锌多金属矿体的成因进行了阐述,对后人在该区域的工作以及同类型矿床的勘查研究工作具有重要指导和借鉴意义。

The Mangya River east region is located in the ore-forming prospect area of Qimantag metallogenic zone in Qinghai Province,its unique structure and dyke development,which controlled the formation and distribution of ore bodies in this area. The geological conditions in this area are complex. Through a large number of geological work in the field,combined with geological achievements,based on analysis of the geotectonic location,geological background,skarn zone characteristics and ore body characteristics of the area,the orecontrolling factors and prospecting indicators were summarized and the metallogenic model was preliminarily established. The causes of iron ore bodies and Pb-Zn polymetallic ore bodies in this area were described,which have important guidance and reference for the work of future generations in the area and exploration and research work of the same type of deposits.
