江西三南地区萤石矿成矿地质特征及找矿潜力
Geological Characteristics and Prospecting Potential of Fluorite Deposits in the Sannan Area of Jiangxi Province
摘要
Abstract
The San'nan area in Jiangxi Province is located in the eastern section of the Nanling metallogenic belt,within the fluorite mineralization zone of northern Guangdong-southern Hunan.This area exhibits highly favorable geological conditions for fluorite mineralization.This study conducted field investigations on newly discovered mineral deposits in the area,summarized the geological characteristics and laws of fluorite mineralization in the Sannan area,and analyzed the potential for fluorite mineralization based on mineral exploration,development and mining development progress.The results indicate that the fluorite deposits in the Sannan area belong to post-magmatic low-temperature hydrothermal filled vein deposits,and the essential conditions for fluorite mineralization are magmatic hydrothermal activity and fault structures.The northeast(north)and east-west trending fracture zones near the contact zone between the Mesozoic high fluoride intermediate-acidic granite body and metamorphic rock basement,as well as the inner and outer contact zones of the red basin,overlaid with hydrothermal alteration such as silicification,are the most favorable for mineralization.The key areas for the next phase of mineral exploration in the region include the peripheral and deep sections of existing large and medium-sized fluorite deposits,fault zones near the inner and outer contact zones of rock masses,and secondary fractures adjacent to the NE-trending deep-seated fault zones.Special attention should be paid to segments within these fractures that exhibit dense quartz veins or fluorite stringers,intense silicification,and pronounced dissolution features.关键词
