摘要
为研究查可勒图石墨矿地质特征及找矿标志,研究区内开展了地质测量、槽探工程、钻探工程以及自然电场法测量等工作.结果表明查可勒图地区晶质石墨矿赋存于古元古代金水口岩群含碳质变质岩系地层中,含矿岩性为含碳质大理岩及石英片岩,经历多期区域变质作用和后期构造岩浆侵入作用,最终形成石墨矿.全区圈定3 条石墨矿带,24 条石墨矿(化)体,矿石矿物为晶质石墨,石墨中固定碳CGD含量为 6.34%,分大理岩型和片岩型两种类型.文章对查可勒图石墨矿床的地质特征进行了阐述,以期为本区石墨矿资源勘查提供参考.
Abstract
In order to study the geological characteristics and ore searching signs of the graphite mine in Chakoletu,geological surveys,trenching works,drilling works and natural electric field method surveys have been carried out in the study area.The results show that the crystalline graphite ore in the Chakoletu area is embedded in the carbonaceous metamorphic rocks of the Jingshukou Group of the Paleoproterozoic era,and the ore-bearing rocks are carbonaceous marble and quartz schist,which were formed by regional metamorphism in several phases and the intrusion of tectonics magma in the later stage,and finally formed the graphite ore.There are 3 graphite ore zones and 24 graphite ore bodies in the whole area,and the ore minerals are crystalline graphite,the fixed carbon CGD content in graphite is 6.34%,and it is divided into two types:marble type and schist type.The article describes the geological characteristics of the graphite deposits in Chakoletu,with a view to providing a basis for the prospect of graphite ore resource exploration in the region.
