Abstract:

During the mining operating in two deposit of Hetai Gold Ore Field,ast rike-slip structure are characteristic indication on gold prospecting at this district,it generally occur on center and top and down of orebodies,and direct influence presence and scale of bonanzas.ln other words,in the ductile shear zone-gold deposit,orebodies controlled by the second-class britt lest ructure of ductile shear zone,it has a angle with main structure-see,and it occer side arrange of littler scale in main structure zone;the strike-slip structure formed by structure of many times activity,that it occur due to differential uplifting along Scmask.Pseudotachy lite on part of structure are that formed by strength fast released when low temperature and high pressure at later period and shallow level,and it not relation of form orebodies.

Key words: Hetai Gold Ore Field, ductile shear zone, divisional strike-slip structure, pseudotachylite brittle structure
