| 中文摘要: |
| 杏枫山金矿地处白马山—龙山东西向构造带与古台山—新宁近南北向构造带交汇处、金山背斜南西倾伏端北西翼,主要断裂构造为北西向断裂。马底驿组第三、第四岩性段的绢英千枚岩金的背景值很高,是金的赋矿层,亦是矿源层。圈出Ⅰ、Ⅱ、Ⅲ 3个石英细脉带,其中Ⅱ号脉带为主矿脉带,Ⅱ号主矿脉带中1、2、4号脉含矿性较好,具较大工业价值。成矿热液来自岩浆岩,属高中温热液型金矿床。据对已知矿体的控制情况,明确提出了区内边深部找矿的具体思路。 |
| 英文摘要: |
| The Xinfengshan gold deposit is located in the junction part of EW-trending Baimashan-Longshan tectonic belt and SN-trending Gutaishan-Xinning tectonic belt, and northwestern limb in the southwestern plunging end of Jinshan anticline. The main fault structure was the northwest trending, the third and fourth member sericite quartz phyllite of Madiyi formation, is ore-bearing horizon,where the gold background value is relatively high. No.Ⅰ, No.Ⅱ, and No.Ⅲ quartz veinlet belts had been outlined, among them, No.Ⅱbelt was the mother lode, and there are economic gold grade in No. 1, No.2 and No.4 gold orebody within No. II mother lode. The ore-forming hydrothermal fluid originated from magmatic rocks and the deposit belongs to high-meso hypothermal type gold deposit. Based on the exploration situation of the known gold orebodies, the prospecting directions in deep and outer areas of the deposit area were proposed for the next stage exploration. |
