摘要
Abstract
The Quannan-Dingnan area belongs to the eastern segment of the Nanling metallogenic belt and the northern Guangdong-southern Hunan fluorite mineralization belt.This region has significant potential for fluorite mineral exploration.Based on field investigations,this study analyzes the geological characteristics,genesis,and metallogenic regularity of fluorite deposits,concluding that all fluorite deposits in the area are epigenetic low-temperature hydrothermal filling vein-type deposits.The fluorite mineralization is controlled by regional NE-trending deep fault zones and secondary NE to NNE-trending faults alongside them.The mineralization exhibits selectivity for host rocks,primarily occurring in Mesozoic Cretaceous-Jurassic and Qingbaikou-Cambrian strata.Indosinian-Yanshanian intermediate-acidic magmatic activities rich in fluorine are most closely related to fluorite mineralization.According to the metallogenic regularity,this paper preliminarily divides the area into 2 metallogenic belts and 4 metallogenic prospective areas,and delineates 9 prospecting targets,providing a basis for further mineral exploration in the region.关键词
