Abstract: The gold and copper orebodies of the Ershiyizhan deposits are different in terms of their spatial distribution. The gold bodies,in a northwestern extension,are located in the southwestern contact of the intrusive,while the copper orebodies are centered inside the intrusive and stretch northeast. Based on the geological features of the Ershiyizhan gold copper deposits,this paper studies the controls factors and proposes a metallogenic model for the deposits:the gold and copper deposits belong to different products of different genesis type and metallogenic periods. The mineralization-related intrusive was emplaced in three times after magmatic differentiation of the crust-mantle mixed magmas.
