青海五一河地区岩浆热液型铁多金属矿床地质特征与成矿模式

青海五一河地区岩浆热液型铁多金属矿床由虎头崖多金属矿区、迎庆沟多金属矿区、景忍铁多金属矿区相连组成,是祁漫塔格地区找矿成果较显著的矿床之一,大地构造位置处于北祁漫塔格早古生代岩浆弧及祁漫塔格早古生代结合部位。本文基于详细的野外工作,从矿床地质特征、矿床的形成构造环境、成矿条件及主要控矿因素,探讨了矿床的成矿机理,在此基础上建立矿床的找矿模式,以指导找矿。

Geological Features and Metallogenic Model of Magmatic-Hydrothermal Iron-Phlymetallic Deposit in Wuyihe Area, Qinghai Province

Abstract: The magmatic-hydrothermal iron-phlymetallic deposits of Wuyihe is one of the most significant deposit on prospecting which is located in binding site of north Qimantage early Paleozoic magmatic arc and Qimantage early Paleozoic. This connected area which is composed by Hutouya, Yingqinggou and Jingren. Based on detailed field work, this paper discuss the mineralization mechanism of the deposit by geological features, tectonic setting, metallogenic conditions and major ore-controlling factors. According to the mineralization mechanism, this paper establishes the prospecting model of deposit that can guide the prospecting.
