Abstract The resource exploration of Hewa area in Liaoning Province was carried out. On the basis of the understanding obtained, the wide field electromagnetic method was used to explore the favorable geological interface for mineralization in this area. The exploration depth and accuracy were greatly improved comparing with the previous work, which was of great significance to the exploration of deep mineral resources in this area. It is the theoretical study of polymetallic ore formation in Hewa area and the gold mineralization model in eastern Liaoning. The establishment of the metallogenic model provides a more accurate geophysical basis.
