| 摘 要： | 马耳夼金矿产于栖霞序列回龙夼单元,岩性主要为英云闪长质片麻岩。区内矿脉受断裂控制明显,成群成带产出,区域性断裂构造与后夼穹形构造交会部位或断裂构造产状变化处是矿体富集的有利部位。NE向断裂、新太古代侵入岩、石英脉是该区金矿成矿的主要控制因素,石英脉为其主要找矿标志,为中低温热液石英脉型金矿床。

| Abstract: | Maerkuang gold deposit locates in Huilongkuang unit of Qixia sequence. Its lithology is mainly tonalite gneiss. Veins in the ore area are obviously controlled by fault structures, and occurred in groups. The intersection part of regional fault structures and Houkuang dome and occurrence changing parts of fault structures are favorable areas of ore enrichment. Fauls with the trend of NE, Archean intrusive rocks and quartz veins are main controlling factors of gold mineralization. Quartz veins are main symbols for ore prospecting. This deposit belongs to medium and low temperature thermal quartz vein type. |
