"Trinity"metallogenic characteristics and prospecting significance of fluorite deposits in Yixian area,western Liaoning Province
摘要
Abstract
The Yixian area in western Liaoning is one of the significant production regions for fluorite deposits in Liaoning Province.Based on the summary of metallogenic geological bodies,ore-forming structures and structural planes,as well as characteristic indicators of mineralization in the region,this study establishes a"Trinity"prospecting prediction model for fluorite deposit in the area.The results indicate that the metallogenic geological bodies of fluorite deposit are Mesoproterozoic carbonate rocks and Middle Jurassic Tiaojishan Formation volcanic rocks.The ore-forming structures are NNE-and NW-trending faults.The ore-forming structural planes include tectonic structural planes and lithological interfaces.The alteration indicators of mineralization are silicification,fluoritization,and kaolinization.The mineralizing hydrothermal fluids are derived from the hydrothermal activities associated with Tiaojishan Formation volcanic rocks.关键词
