Abstract: Xilinhe brittle-ductile shear zone is a important part of Fuerhe-Gudonghe lithospheric deep fault and consisted of three brittle-ductile shear faults (F₁, F₂, F₃ in the east; F₄, F₅ in the central; F₆ in the west). In the east belt, the brittle deformation, about 4 km long, is the major structure; in the central belt, are the brittle and plastic deformations, about 5km; in the west belt, is the plastic deformation, about 5.5km. Tectonite developed well and can be classified into two series of brittle deformations and plastic deformation. The deformation and retrea ted metam orphism developed simulta neously. Them etallog enicage of Xilinhe gold ore was Yanshanian period. Xilinhe brittle-ductile shear zone is the conducting and host structures of gold ore. Based on the geological condition for mineralization of prospected deposit, we should make a follow-up prospecting in the extending direction of the six orebodies. According to the view of marginal mineralization, the explo ration can be carried out in the contact zone of Archean grey gneiss and Protero zoic light metamorphic rock, and five prospecting criteria have been determined.
