Overview

P618.41; The Mujicun Cu (Mo) ore deposit at Laiyuan,Hebei Province,is a currently proven large-sized Cu (Mo) polymetallic ore deposit and it is located in the second-ordered fault depression basin of the ditachment belt on the hanging-wall on the western side at the juncture of the Laiyuan dumbell-shaped complex in the northern part of the Fuping mantle-branch structure.Metallogenesis is controlled by diorite porphyrite in intrusive relation with the fault depression basin and other relevant fault structure systems and intenstive wall-rock alteration zones.This study,in conjunction with the most recent exploration data,analyzed the geological background of metallogenesis of this deposit,summaried the geological characteristics of typical ore deposits,determined the alteration zonation of the deposit,investigated regional metallogenesis and the genesis of typical ore deposits,discussed the regional ore-forming and ore-controlling structures,and generalized the regional ore-controlling model and metallogenic model of the deposit.It is considered that the Mujicun porphry Cu (Mo) deposit,the Tieling,Futuyu,Xiaoligou and other skarn-type Fe-Cu deposits and the He'ergou hydrothermal-type Pb-Zn-Ag deposit jointly constitute a three-in-one polymetallic orefield,with the characteristics of typical metallogenic series.
