    Abstract
  • Jinlonggou gold deposit is the first large-scale gold deposit discovered in the metallogenic belt of northern Qaidam Basin, Qinghai province. Based on the previous research data and the analysis of the geological background, deposit characteristics, ore quality, metallogenic stages and alteration, the authors considered that Jinlonggou gold deposit is a composite superimposed epithermal one formed in a two-stage mineralization: Late Silurian (425-400 Ma) metamorphic metallogenic period and Middle Devonian (374 Ma) magmatic hydrothermal metallogenic period. The main metallogenic period is Middle Devonian magmatic hydrothermal metallogenic period, which is closely related to the magmatic activity of granodiorite porphyry complex in this era. The tectonic metallogenic environment is late Caledonian continental crust subduction and collision, and early Variscan post-orogenic intracontinental uplift. The pattern of ore-controlling structure is NW-trending shear zone + near NE-trending fold + detachment fracture. The spatial distribution of ore-controlling structure indicates that there is little prospecting potential in the deep part and in the strike of Jinlonggou gold mine. The areas with secondary folds and fracture structures superimposed in the first-class ore-controlling structure (regional NW-trending ductile shear zone) are favorable gold metallogenic location and prospecting.
