Abstract
Yuantaizi Township in Xingcheng City is located at the northeastern margin of the North China Craton.Due to the subduction of the Pacific Plate,crust-mantle mixed magmas were formed.During the upward intrusion,numerous metallic elements were captured,and finally,a polymetallic ore body was formed after cooling.The strata in the study area are mainly marine strata of the Changcheng System of the Mesoproterozoic;numerous faults are developed.Magmatic and hydrothermal activities are intense,making the area favorable for the mineralization of various metals such as silver,copper,and molybdenum.The ore bodies exhibit polymetallic mineralization of silver,lead,zinc,copper,molybdenum,etc.The main ore-forming minerals include argentite,galena,sphalerite etc.The ore bodies are of intrusive magmatic hydrothermal genesis,and they were formed in the early Yanshanian period of the Mesozoic era.The prospecting marks include structural marks,magmatic rock marks,surrounding rock marks,alteration marks,etc.and these prospecting marks are concentrated in the variable segments of the contact zone structure.关键词
