摘要
阿拉善左旗位于古亚洲构造域塔里木板块亚域(Ⅲ)北山造山带(Ⅲb)旱山—亚干地块(Ⅲb)亚干隆起(Ⅲb2)中段的北部,各类金属、非金属矿产资源较为丰富.本文通过总结地质勘查成果,对白云石大理岩矿矿体特征、产状及规模、矿石矿物成分、结构构造、矿石自然类型分析研究,并对矿床成因进行了初步探讨,认为该矿床白云石大理岩矿体的形成是受区域变质作用及岩浆活动共同作用的影响,为矿区进一步生产工作及区域同类型矿床找矿提供参考.
Abstract
Alxa Left Banner is located in the northern part of the middle section of the Tarim Plate Subdomain(Ⅲ)and the North Mountain Orogenic Belt(Ⅲb)of the Paleo Asian tectonic domain.It is rich in various metal and non-metallic mineral resources.This article summarizes the geological exploration results of the mining area in recent years,analyzes and studies the characteristics,occurrence and scale,mineral composition,structural and structure,and natural types of three dolomite marble ore bodies,and preliminarily explores the genesis of the deposit.It is believed that the formation of the dolomite marble ore body in the deposit is influenced by the combined effects of regional metamorphism and magmatic activity,provide reference for further production work in the mining area and prospecting for similar deposits in the region.
