Hornfels occurs widely in such copper deposits and gold deposits of the Gangdise metallogenic belt in Tibet as Jiama, Qulong, Liebu, Xiongcun, Zemoduola and Nongruri. In ore prospecting, extensive cover of hornfels suggests the existence of huge heat source in the deep, and the change of its thickness and mineralization can provide useful information concerning the central position of the deep rock body. Hornfels in Xiongcun was formed through the thermal metamorphism caused by the intrusion of Himalayan biotite granodiorite into tuff after mineralization, thus failed to affect the mineralization. In the prospecting process, the ground magnetic survey of copper ore body and wall rock including hornfels will be useful in determining the location of mineralized body in the depth.
