Based on the comprehensive analyses of the geology of Xicheng concentrated mineralizaion area in Qinling Mountain, the lead-zinc metallogenesis here consists of Caledonian (before the main metallogenic period), Hercynian (earlier stage of the main metallogenic period), Indosinian (later stage of the main metallogenic period) and Yanshanian Epochs (after the main metallogenic period); the type of lead-zinc deposits differs over geologic time and the metallogenisis is associated with the regional geology，especially with the Devonian extention and fault-depression and the late Trassic intracontinental orogeny. The former geologic process resulted in the hotwater sedimentary basin and exhalative-sedimentary metallogenesis, while the latter one resulted in the extensive regional tectonism-megmatism, which is the reformation of the local lead-zinc deposits.
