| 中文摘要: |
| 广水—红安地区萤石矿带是湖北省萤石矿重要的成矿区带之一，为找到新矿体，突破找矿中的关键性问题。通过野外调查及对区内萤石矿成矿地质背景、矿床地质特征、成矿地质条件、成矿规律的研究，认为该区萤石矿受区域性北西向深大断裂带控制，矿体、矿脉主要沿晚期叠加的北（北）东向断裂裂隙分布；赋矿围岩主要为红安岩群中含有大理岩、白云石英片岩的岩性组合；燕山期中酸性花岗岩与萤石矿成因关系最为密切。最直接的找矿标志为北（北）东向具硅化、重晶石化、萤石矿化等热液蚀变的断裂破碎带，已知矿床的深部、具矿化异常的相似构造破碎带和北西向新城—黄陂断裂带的次级构造带是主要的找矿方向。研究成果可为今后区内开展进一步的萤石矿勘查提供依据。 |
| 英文摘要: |
| Guangshui-Hong'an area is one of the important fluorite metallogenic belts in Hubei Province. In order to find new orebodies and identify the key factors on controlling orebodies. Based on the field investigation and the study on the metallogenic geological background， geological characteristics， metallogenic geological conditions and metallogenic law of the fluorite deposit in this area， it is believed that the fluorite deposit in this area is controlled by the regional deep NW-trending faults， and the orebodies and veins are mainly distributed along the late superimposed NW-trending faults. The surrounding rocks are mainly marble and dolomitic quartz schist of the Hong'an group. The genesis of the Yanshanian medium acid intrusive rock is most closely related to fluorite deposit. The most direct prospecting indication are the NE-trending fracture zones with hydrothermal alteration such as silicification， barittization and fluorite mineralization. The deep area of the known ore deposit， the similar structural fracture zone with mineralization anomaly and the secondary structural zone of the Xincheng-Huangpi fault in the northwest direction are the main prospecting directions. This study can provide theoretical support for further fluorite exploration in this area. |
