     Xunyang Lanmugou area is in the eastern section of gold and polymetallic metallogenic belt of southern Qinling orogenic belt. On the basis of researches in the past few years, this paper adopts modern orogenic belt theory to study the tectonic settings, strata, lithological, tectonic and geochemical characteristics of gold mineralization in this area. It is indicated that the Lower Silurian black rock series of second lithologic section is the material source of the gold deposit of this area. South Qinling Indosinian-Yanshanian intracontinental orogeny gave rise to the massive basement decollement and overthrusting of the tectonicslices between giant nappe fault zones, which was the source of dynamics in the formation of gold mine in Lanmugou area; Hehumiao ductile shear zone is the most important ore-controlling factor in the enrichment and metallization of gold mine in the Lanmugou area.
