摘要
兴国城岗—永丰南坑地区是江西省重要的萤石成矿区,属于江西省赣南区—南岭成矿带雩山钨、锡、铀、金、稀土多金属,萤石非金属成矿亚带。本文通过对区内地层、构造、岩浆岩以及典型萤石矿床特征进行总结分析,发现研究区内萤石矿主要产出于中生代岩浆岩与含钙地层内外接触带的断裂构造带内,北东、北北东向构造为主要的控矿断裂,并初步总结了区内萤石矿控矿因素及找矿方向。本文研究成果对该区今后的萤石矿找矿工作具有实践指导意义。
The Xingguo Chenggang-Yongfeng Nankeng area is an important fluorite metallogenic region in Jiangxi Province.It belongs to the Gannan-Nanling metallogenic belt of Jiangxi Province,specifically the Yushan W,Sn,U,Au,REE polymetallic and fluorite metallogenic sub-belt.This study summarizes and analyzes the characteristics of the regional stratigraphy,structures,magmatic rocks,and typical fluorite deposits.It finds that the fluorite deposits in the study area are mainly hosted within faulted structural zones occurring along the contact zones between Mesozoic magmatic rocks and calcium-bearing strata.The NE and NNE-trending structures serve as the predominant ore-controlling faults.The paper preliminarily summarizes the ore-controlling factors and prospecting directions for fluorite deposits within the area.The findings of this research provide practical guidance for future fluorite prospecting work in this region.
