Geological characteristics and genetic analysis of Liuhejia graphite deposit in Pingdu,Shandong
The Liuhejia graphite mine is located on the eastern side of the Yishu Fault Zone,at the junction of the southern margin of the Jiaobei uplift and the Jiaolai depression.The study area has complex structural features,with exposed strata mainly consisting of the Jingshan and Yetou formations of the Paleoproterozoic Era,providing excellent mineralization conditions.Based on the regional geological background characteristics and geological survey,the geological characteristics and ore control laws of the deposit were further identified through field geological survey,rock ore identification,rock geochemical test and analysis.This article provides a comprehensive summary of the characteristics of nine ore-forming elements,as well as the genesis,mode of ore formation,prospecting rules,and indicators for graphite deposits in the study area.The findings are of significant reference value for the exploration of similar graphite deposits in China.
