Geological Characteristics and Genesis of Guogou Fluorite Deposit in Luanchuan County,Henan Province
The Guogou fluorite deposit in Luanchuan county is a newly discovered fluorite deposit in Heyu area.There are two large fluorite ore belts developed.Three new fluorite ore bodies have been discovered,which are strictly controlled by the fault structure and are 600～1200m long.The previous studies on ore-forming material source,ore-forming age,inclusions and isotopes of the fluorite deposit in the region show that the fluorite deposit was formed in 118～126Ma and belongs to the Early Cretaceous in the region.The ore-forming fluid is low temperature,low salinity and low density fluid,which may mainly originate from atmospheric precipitation.The Heyu pluton and Taishanmiao pluton are the host surrounding rock and probably important material sources of fluorite deposits.By comparing the geological characteristics of the mining area and the characteristics of the ore body with those of the regional fluorite deposit,it is found that the Guanguou fluorite deposit may have similar mineralization with the fluorite deposit in the region,so it is considered that the genetic type of the Guanguou fluorite deposit is fault-controlled and medium-low temperature hydrothermal fissure filling vein deposit,and the deep part of the deposit has great prospecting prospect.
