Geochemical characteristics and prospecting prospect assessment of eastern Liujiang Basin,Hebei Province
Liujiang Basin is located in the middle of the Sino-Korean quasi-platform.It has a complex structure,strong magmatic activity,and superior regional metallogenic conditions.In order to achieve a breakthrough in prospecting,the geo-chemical anomaly characteristics of the AS38 region in this area were comprehensively studied using 1:50 000 stream sediment survey,1:10000 soil geochemical detailed survey and mineral spot inspection.The results show that the anomaly enrichment center of Cu element is prominent,the coefficient of variation is high,and the Cu element is well integrated with Au,Ag,Cr,Mo,etc.The soil geochemistry results show that the Cu anomalies are widely distributed,with high intensity and pronounced zonation,are closely related to the high-temperature elements Mo and W,and are well integrated with Au and Ag.In the ab-normal zone,the mineralization is mainly copper mineralization,with local gold and silver mineralization points.Therefore,the study area has a significant prospecting prospect for copper polymetallic ore,and the fracture structure development zone near the rock mass is the fundamental direction of the subsequent prospecting.
