摘要
马依当石墨矿床产出在上志留-下泥盆统红柳沟组中,红柳沟组为一套含碳质绢云母片岩及砂岩;马依当石墨矿床的形成经历了沉积、区域变质及热液变质改造等3个时期。通过对该矿区成矿地质特征、矿体特征等研究,得出了成矿期次、成矿模式及找矿标志;认为马依当一带石墨矿床属沉积变质+热液改造型成因的晶质石墨矿床。
He Mayidang graphite deposit occurs in Upper Silurian-Lower Devonian Hongliugou Formation consisting of a set of carbonaceous sericite schist and sandstone.The ore-forming process includes three main stages:sedimentation,regional metamorphism and hydrothermal metamorphism.The metallogenic stages,model and prospecting marks are established based on studying the metallogenic geological characteristics and ore body charateristics.It is considered genetically that it is a sedimentary metamorphism-hydrothermally transformed type crystalline graphite deposit.
