Study On Typical Gold Deposits And Exploration Potentiality In Sarekebayi Basin?wuqia County, Xinjiang

The base gold deposit in the Sarekh Bayi Basin is located on the northern edge of the Tarim Block,in the south of the southwestern Tianshan orogenic belt,and within the sub-zone of the East Alaijin Ore.The area has excellent metallogenic geological conditions.By comprehensively analyzing the characteristics of metallogenic geological conditions,geochemistry,geophysics,and remote sensing information in the study area,the geologic features and genesis of the deposits are summarized,and prospective prospects are delineated by using remotely integrated geophysical information.The mining area is mainly located in the contact zone between the Bashisuogong Formation of the Carboniferous and the fifth lithologic-order fault of the Aksu Group of the Great Wall System.The tectonic action is strong.There are multiple fault structures in the north-east direction and the brittle-ductile shear zone.These secondary structural shears Cutting zone is the main ore-controlling ore-controlling structure.Summarize the geological features of gold ore bodies and explore the genesis of the deposits through studies of rock geochemistry,isotope geochemistry,and fluid inclusions.The occurrence status of gold elements was analyzed using the field and microscopic features of rocks and ores.The results of remote sensing alteration information not only agree well with the mineralization alterations in the field,but also coincide well with the brittle-ductile shear zone near the fault contact zone in the study area,indicating that the formation and structure of the deposit are closely related.The remote sensing alteration information extraction results are in good agreement with the field mineralization alterations,and through the structural interpretation of the study area,it was found that the brittle ductile shear zone near the fault contact zone in the study area is well consistent with the interpretation results.The formation of this deposit is The structure has a close relationship,and the results of remote sensing interpretation can serve as the basis for delineating the prospects.In addition,the data inversion of a geophysical and geophysical prospecting profile through a magnetic method shows that there is an insidious and steeply dipping structure related to silicification and intrusive sulphide near the ore deposit.This structure also provides a favorable basis for prospecting in the future.Combined with the geological characteristics of mineralized bodies and the genesis of mineral deposits,as well as the results of physical and chemical exploration and remote sensing interpretation,comprehensive information analysis was conducted on the mining area to delineate the metallogenic prospects.Combining with previous research achievements and existing conditions,the base gold deposit in Sarekh Bayi Basin has certain prospecting potential.
