Geological Characteristics and Genesis of Daping Fluorite Deposit in Shaowu City,Fujian Province
Daping fluorite mine is located in the middle of Shaowu-Jiangle fissure in north Wuyi uplift area,located in Pucheng Yankeng-Shaowu Zhangcuo fluorite metallogenic belt.The ore bodies are mainly lens-like and vein-like distributed in the northeasterly fault tectonic zone of the granite.The boundary between the ore bodies and the surrounding rock is clearr,and it has the typical characteristics of filling deposit.Based on the summary and analysis of the metallogenic geological conditions and geological characteristics of the deposit,it is tentatively concluded that the metallogenic process of this deposit can be roughly divided into the early metallogenic stage and the late metallogenic stage,which belongs to the medium and low temperature hydrothermal filling type formed after the magmatic period.The main ore-controlling structure of the fluorite deposits in the area is the NE-trending fracture zone in the Late Jurassic oligobasic and fine-grained syenite granite.The areas with intense pyrophyllite,cataclastic and chlorite mineralization in the fault zone are are the direct prospecting signs.
