Abstract: The Gaoliying Fluorite Deposit, which located in the Guojiatun-Hanjiadian Fluorite-Pb-Zn-Ag Metallogenic Area, is a newly discovered medium-sized fluorite deposit. Through detailed field geological survey and comprehensive study, this paper analyzes the geological characteristics and genesis of the Gaoliying Fluorite Deposit. This deposit is strictly controlled by faults, and it is a medium and low temperature hydrothermal filling fluorite deposit. The minerogenetic epoch is limited to the early cretaceous, and it presents the characteristics of multi-stage metallogenic superposition. The F-containing hydrothermal liquid evolved in the later stage of magmatic activity mixed with atmospheric precipitation in the ascending process, leachated Ca from the surrounding rock, enriched and formed the Gaoliying Fluorite Deposit in the favorable position of structure.
