| 中文摘要: |
| 白山市板庙子金矿床主要赋存于古元古界老岭群珍珠门组大理岩与新元古界青白口系钓鱼台组石英砂岩的角度不整合界线与NE向大型断裂带的交汇部位,具有层位与断裂共同控矿的特点。通过对板庙子金矿矿区地质、矿床地质特征的论述及矿源层、控矿构造等控矿因素的讨论,认为矿区特殊的构造环境和物化条件(氧化还原条件及温度、压力突变)使之形成独特的矿物组合及结构构造,是中国的一个新类型金矿床。 |
| 英文摘要: |
| Banmiaozi gold deposit is located at the intersection of NE-trending fractural belt and angle unconformity between marble of the Early Proterozoic Zhenzhumen formation and quartzite of Diaoyutai formation of Neoproterozoic Qingbaikou System and controled both by horizon and fractural belt.This paper deals with geological characteristics of the mine area and the gold deposit and discusses ore-control factors, such as the source bed and host structure indicating that the gold deposit is formed under special structural setting (abrupt change of Redox condition,temperature and pressure) with unique mineral assemblage and ore texture and structure. It is a new type of gold deposit in China. |
