| 中文摘要: |
| 大瓜冲锑矿位于牛头寨复式背斜的北西扬起端,锑矿床严格受断裂和褶皱构造控制。锑矿体根据其产出位置及赋矿围岩的不同可划分为三种类型:(1) 产于主断裂破碎带中的矿体；(2) 产于主断裂下盘硅质岩中的矿体；(3) 产于断裂上盘层间破碎带中的矿体。矿区成矿物质主要来源于深部隐伏花岗岩体,成矿期属印支期,矿床属岩浆期后低温热液充填型锑矿。 |
| 英文摘要: |
| The Daguachong antinomony ore area locates at the northernwest lifting portion of Niutouzhai complex anticline. The ore depositt is strictly controlled by the structure of fault and fold. Th ore body is classified to three types according to its occurring position and ore bearing rock:1. ore body in the main fractured zone, 2. ore body in the down faulted block with cataclastic silica rock, 3. ore body in the interformational fracture within the upper faulted block. The metallogenetic material mainly came from deep blind granite. The metellogenetic period is Indo-chinese epoch. The ore deposit is defined as post-magma epoch epithermal deposit. |
