Gold Deposits In The Mineralization Process And Prospecting Target Areas Of Lou Li

In southern part of Taihang mountain Fe polymetallic metallogenic belt,the Han-Xing region of southern Hebei province is the important skarn iron deposit concentration area in china(Han-Xing iron deposit).Previous research on the region's iron ore is very deep,however,in addition to iron ore other metal minerals found in this area is less.Iron ore has dried up because of all the year round mining,so looking for a new species of mineral resources is necessary.Louli gold deposit is located in Yongnian Handan city,Hebei province and between Handan major fracture and Drum mountain-Purple mountain fracture,which is the polymetallic mineralization favorable position.Volcanic eruption in the region is very strong and volcanic mechanism is controlled by regional tectonic.At present,four gold mineralization alteration zones have been circled in Louli area,but for Louli gold deposit the understanding of deposit genesis is not clear enough.On the basis of the large scale geological mapping and measured geological sections,the study area geology background and geological features of gold deposits are summarized and a comprehensive analysis.Through the analysis of gold ore sample for inclusions in the study area,the article summarizes the gas and liquid phase characteristics of fluid inclusions,tests the inclusions homogenization temperature and salinity and calculates the metallogenic pressure and depth.By hydrogen and oxygen isotope,sulfur isotope,lead isotope and rare earth elements tracer,the source of the gold deposit ore-forming materials is identified,So the type of gold deposit is identified and the metallogenic model and metallogenic regularities of gold deposit are summarized.On the basis of the research on the metallogenic regularity,5 prospecting targets are delineated,which combine with geochemical anomalies of different scale,providing the direction and scope for the subsequent prospecting work.
