| 中文摘要: |
| 内蒙古哈达门沟地区是华北陆块北缘重要的金矿集中区之一,金矿体主要产在乌拉山岩群变质岩中,矿石类型主要为石英脉型、石英-钾长石脉型和钾硅化蚀变岩型,具有多期成矿的特点,主成矿期为印支期。在成矿地质背景研究、矿床地质特征、控矿因素和找矿标志分析的基础上,结合区域地球物理、地球化学资料和近年来的勘查成果,认为矿区深部和外围仍有很大的找矿潜力。 |
| 英文摘要: |
| The Hadamengou area, located in Inner Mongolia, is one of the most important gold-concentrated area in the North Margin of North China Block. Gold ore bodies are hosted in metamorphic rocks of the Wulashan Group, the major ore types are quartz-vein type, quartz-potash feldspar-vein type, and potassic-silicification altered rock type. Gold mineralization is characterized by multiple stages, mainly formed at Indo-Chinese epoch. Based on the study of metallogenic geological setting, geological features of ore deposit, ore controlling factors, and prospecting criteria, in combination with regional geophysical and geochemical data and geological exploration results in recent years, it is proposed that the depth and periphery of mining area is of great prospecting potential. |
