内蒙古达茂旗查干文都日区石墨矿地质特征及开发经济意义

摘要

查干文都日石墨矿为赋存于中元古界白云鄂博群尖山组一段（Chj1）含石墨变质岩系地层中的沉积变质型矿床，严格受地层层位控制，含矿岩性为粉砂质炭质板岩，经历多期区域变质作用形成。该文对矿床的构造背景、矿床地质特征进行了阐述，对石墨矿床开发进行了初步探讨。%Zhaganwenduri graphite deposit occurrences in Jianshan Formation (Chj1) containing graphite sedimentary metamorphic type ore deposit of metamorphic series stratum, Baiyun`ebo Group of Mesoproterozoic Erathem, which is strictly controlled by stratigraphic horizon, ore-bearing lithology is silty carbonaceous slate, formed by multiperiodic regional metamorphism. In this paper, the tectonic setting, ore deposit geological features of the ore deposits were expounded;the graphite deposit development was preliminary discussed.
