The Xiaoqinling-Xiong’ershan region in the Qinling Mountains central China, lies about 30-50 km inland of the southern margin of the North China craton, has an indicated resource of more than 400 tonnes of gold and an annual production of 16.5 t Au, which is second in China only to the Jiaodong gold province (Mao et al., 2002). Gold deposits in the Xiong’ershan area are distributed to the north of the Machaoying fault, mainly surrounding the Huashani and Heyu granite plutons, which have been dated by SHRIMP Zircon U-Pb methods of 130 and 127 Ma, respectively. The Miaoling gold deposit is a typical deposit occurring as disseminations in fractured and altered metamorphic rocks in the Xiong`ershan area. Based on the REE composition of the Au-bearing pyrite, This paper traced the source of the ore-forming materials.
