Tectonic Deformation Styles and Dynamics of Gold-Polymetallic Deposits in Fengtai Apart-Pull Basin of Shaanxi Province in Relation to Gold Mineralization

摘要

///The studied apart-pull basin was formed during the oblique-direction subduction and collision of the Huabei and Yangtze Plates. The tectonic deformation history, styles, dynamics, records of tectonic lithofacies and large-scale migration of fluids in the apart-pull basin constitute some of the most important problems in the continental dynamics, and the study of these problems are helpful to the detailed investigation of the mineralization regularity and the controlling factors of polymetallic deposits, Carlin-type gold deposits and similar ore deposits in the West Qinling orogeny. The Carlin-type and similar gold deposits were controlled by “W-M”-type multiple syncline plus brittle-ductile shear zone. Moreover, the Baguamiao gold deposit characterized by multiple stages of gold mineralization, a deposit similar to Carlin-type gold deposit, was controlled by overturned syncline and brittle-ductile shear zone, while the Wenjiangsi gold deposit, a Carlin-type gold deposit, was controlled by syncline and brittle fault zone.
