Analysis On Fault Structure And Metallogenic Prediction Of Guilaizhuang Gold Mine In Shandong Province

Guilaizhuang gold mine is located in the southeast of Tongshi Town,Pingyi City,covering an area of 15 square kilometers..The Guilaizhuang gold mine is the largest gold mine in western Shandong Province,Deep and peripheral explorations have been conducted for many years in the study area.However,In recent years,in various parts of the region has been continuously in-depth exploration,but little progress has been made.This has caused serious resource crisis and affected the follow-up production of the mine.At present,there is still a lack of overall understanding of the ore-controlling structures system of the Guilaizhuang mining area,especially the study of ore field structure is still blank.It is urgent to strengthen the study of ore-controlling structures to achieve new replacing resources breakthroughs.This thesis deeply studied the past geological data,analyzed the geological characteristics of the Guilaizhuang gold deposit,studied and analyzed the ore-controlling structures of the Guilaizhuang gold deposit,summarized the structure-controlling laws,and carried out the prospecting prediction of the Guilaizhuang mining area.Through this research work,certain results have been achieved: carefully analyzing the characteristics of ore-controlling structures,ore body and ore types of the Guilaizhuang gold deposit,and summarizing the gold metallogenic rules and its spatial distribution;clarifying the time and space distribution characteristics of fault structures were clarified,indentifying the relationship between different faults,and determining the three-dimensional tracking and properties of important fault structures;making new breakthrough about understanding of the ore-controlling structure: the conjugate X fault is considered to be the most important ore-controlling structure in Pingyi area.The Guilaizhuang F1 fault is a trace-open structure.The X conjugate fault controls the gold ore body in the plane and the vertical direction.The study of mineralization prediction has been carried out in the deep part of Guilaizhuang mining area,which provides a reliable basis for further prospecting.
