Enrichment Regularity And Metallogenic Prediction Of Crystalline Graphite Deposit In Xigola Mining Area,Qinghai Province

The Xigola graphite deposit is located in Aljin metallogenic belt,which is the concentration area of mineral resources in Qinghai Province.In the past,the crystalline graphite deposit in the Daken Osaka group was found in the Aljin area,and the higher grade crystalline graphite ore body was found in the Xigola area.The discovery of the higola crystalline graphite deposit further developed the Aljin metallogenic belt and even the whole Qaidam A new way to look for crystalline graphite deposit around the basin.However,the study area is lack of ore-forming conditions,ore-controlling factors,ore-forming conditions,enrichment rules of graphite ore and ore-forming prediction research,and the prospecting work in the study area is slow.Therefore,strengthening the enrichment rules of crystalline graphite ore and ore-forming prediction research in the study area has practical significance for determining the prospecting direction in the study area.On the basis of detailed field geological data and comprehensive analysis,combined with theoretical knowledge of deposit science,mineralogy,geophysics,etc.,this paper studies and analyzes the metallogenic relationship between strata,structure,magmatic rock and crystalline graphite ore,enriches the theoretical analysis of metallogenic prediction in the study area,and expands the prospect of prospecting.This study mainly uses 1:10000 IP middle ladder survey,trenching engineering,light slice analysis and other means to study and analyze the geological background of the mineralization of the Graphite Deposit in the area,the characteristics of the relationship between the graphite ore belt and the fracture alteration belt,the characteristics of the ore body and the ore,and summarizes the metallogenic conditions,prospecting criteria,and the law of the enrichment of the graphite ore.The Xigola graphite deposit in the Aljin metallogenic belt is typical.The main ore mineral of the graphite ore is crystalline flake graphite.In the study area and region,the main goal is to find the regional metamorphic crystalline graphite deposit.according to the metallogenic elements,the metallogenic prediction is carried out for the metallogenic favorable parts of the study area,and two prospecting targets are delineated.
