| 中文摘要: |
| 李沟矽线石矿床位于“豫西南高铝三石成矿带”中,受区域地层、构造及岩浆活动影响显著,属沉积变质矿床。该矿床赋存于古元古界雁岭沟组片岩内,矿床受地层和褶皱构造控制,矿体呈层状产出,成矿地质条件较好。本文在研究前人地质勘查资料的基础上,总结了该矿床的区域及矿区成矿地质条件,并对该地区矽线石矿的矿床成因、找矿标志进行了探讨。笔者认为李沟矽线石矿床及区域地层、构造、岩浆活动构成了“三位一体”的控矿机制,该矿床的周边地区内矽线石矿床(点)分布较多,李沟矽线石矿床及外围地区具有寻找矽线石矿的较好找矿前景。 |
| 英文摘要: |
| Ligou silicite deposit is located in the “high-alumina three-stone mineralization belt in southwest Henan”, which is significantly affected by regional strata, structure and magmatic activity, and is a sedimentary metamorphic deposit. The deposit is deposited in the schist of the Yanlinggou formation of the Paleoproterozoic Boundary, and the deposit is controlled by stratigraphic and fold structures, and the ore body is layered and produced, and the mineralization geological conditions are good. On the basis of detailed geological exploration data, this paper summarizes the area of the deposit and the mineralization geological conditions of the mine, and discusses the causes and prospecting markers of the deposit of the siliconite ore in the area. The author believes that the strata, structure and magmatic activities of the Ligou silicite deposit and the regional area constitute a “trinity” ore control mechanism, and the silicite deposits (points) in the surrounding areas of the deposit are more distributed, and the Ligou silicite deposit and the peripheral areas have a good prospect for finding silicite ore. |
