都兰县迈龙地区金多金属矿矿体地质特征与找矿远景分析

Geological Characteristics and Prospecting Potential of Gold Polymetallic Deposits in Mai Long Area of Dulan County

研究区大地构造位置位于东昆仑前峰弧南侧复合拼贴带东段的北部。雪山峰—布尔汉布达造山亚带中的雪山峰—布尔汉布达华力西—印支期钴、金、铜、玉石(稀有、稀土)成矿带东段,成矿条件优越。对研究区地层、构造、岩浆岩、矿体特征及围岩蚀变进行了详细分析,进而对矿床成因及找矿标志进行研究,最后分析了该区域的找矿远景。

The geotectonic position of the area is located in the northern part of the eastern section of the compound collage belt on the south side of the front peak arc in East Kunlun.There is a snow mountain peak of the boolanboda orogenic belt in the snow mountain peak-the eastern segment of the cobalt,gold,copper and jade(rare and rare earth)metallogenic belt of the boolanboda Indo period.It has a favorable metallogenic condition.This paper makes a detailed analysis of the strata,including structures,magmatic rocks,ore bodies and rock alteration in the area.Then,we tell of the genesis and prospecting criteria of the deposit to analyze the prospecting prospect.
