The Shenjiaya gold deposit is a representative one in the Xuefeng Mountains, western Hunan Province. The RbSr isochron age of the inclusions in quartz from the deposit is 90.6±3.2Ma，which indicates that the mineralization happened during the Yanshanian Period. Orebodies of the deposit are strictly controlled by the fourth Member of the Madiyi Fm., Neoproterozoic Banxi Group and the gold mineralization might be related to large scale of regional thrustnappe events，and the deposit should be attributed to tectonic hydrothermal origin.
