银钼矿成矿地质条件分析银钼矿成矿地质条件分析 摘要：架子山矿区位于归流河镇北西 190km，行政区划隶属内蒙古自治区兴安盟科尔沁右翼前旗索伦镇管辖。《内蒙古自治区科尔沁右翼前旗架子山矿区Ⅰ区银钼矿详查报告》由内蒙古矿业开发有限责任公司提交。完成 1:1 万地质草测 86.39km2,1:1000 地形地质测量 1.44km2，钻探进尺 43437.74m，选矿试验样 1 件。后探明矿体赋存于上侏罗统玛尼图组安山岩与侏罗纪钾长花岗岩的内外接触带，尤以内带为甚，与成矿有关的岩体为侏罗纪花岗岩，构造以北东、北西向为主。 关键词：内蒙古科尔沁右翼前旗架子山矿区 Abstract: Jiazishan mining areadistrict is located in the North West 190km of Guiliuhe Town, administrative division under the Suolun Town of Horqin Youyi Qianqi in Xing ' an League of Inner Mongolia.Inner Mongolia mining development limited liability company submitted“The Detailed Report of the Silver-molybdenum ore (ⅰ) district in Jiazishan mining area of Horqin Youyi Qianqi of Inner Mongolia”. The coverage of 1:10K simple geological survey is 86.39km2. The 1:1000 terrain and geological measurement coverage is 1.44km2. The drilling footage is 43437.74m long. The ore-selection sample amount is 1. The later work proved that the ore body occurrence is located in both inside and outside of the contacts area of the andesite in Manitu Group of Upper Jurassic and the Feldspar Granite of Jurassic, the inner part is of better. The rock body related to mineralization is Granite rock of Jurassic. The construct of ore body is mainly North East and North West.
