| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
