Abstract

The Yongshan area of Leping City belongs to the front of the tower in the east section of the Qinhang metallogenic belt-Fuchun copper polymetallic ore-forming belt. Based on 1:10,000 soil geochemical survey in this area, the authors analyzed elemental geochemical characteristics, single element anomaly characteristics and elemental combination characteristics. In combination with the geological background of mineralization, a total of 18 comprehensive anomalies were identified, and the comprehensive anomalies were classified and evaluated. Preferably, 3 better anomalies were verified in detail. The surface exploration trough revealed 2 new gold (chemical) sites, 2 gold orebodies and 2 gold mineralized bodies, thus obtaining a good ore prospecting effect. It is believed that the ore-search prospects in the area are good, and a skarn-type copper deposit is expected to be found. This area is the favorable area for finding ductile shear gold deposit.

Key words： soil geochemical survey anomaly characteristics ore-search prospects gold deposit Yongshan area of Leping City
