| 中文摘要: |
| 辽宁省彰武县赵家沟金矿位于冀东—辽西金成矿带东缘，矿区共发现36条金矿化体，其中有8条主矿体，主要发育在19条北北西向断裂构造蚀变带中。该矿床矿石呈他形粒状结构，角砾状、脉状构造，金矿物以自然金和银金矿为主。通过矿床地质特征分析，初步推断赵家沟金矿床成因类型为低温热液型金矿，同时提出区内的断裂构造、石英脉以及矿化蚀变为主要的找矿标志，并指明后期找矿工作中应加强对构造蚀变带及深部矿体的控制。 |
| 英文摘要: |
| The Zhaojiagou gold deposit is located at the eastern margin of the Eastern Hebei-Western Liaoning gold metallogenic belt. Thirty-six gold mineralizations bodies were found in the mining area. Among them, eight orebodies are the main ore bodies. They are mainly developed in nineteen NNW-trending alteration zones of fault belt. The ore minerals are mainly natural gold and silver gold mines. And ore structure have heteromorphicgranular structure, brecciated structure and vein structure. Through the analysis of the geological characteristics of the deposit, this paper is preliminarily inferred that its genetic type is low-temperature hydrothermal gold deposit. At the same time, it is suggested that the fault structure, quartz veins and mineralization alteration in the area are the main prospecting indicators. And it is pointed out that the control of structural alteration zone and deep ore body should be strengthened in the later prospecting work. |
