Abstract

Abstract

The Tianziping gold deposit in West Qinling orogenic belt is an altered rock type gold deposit with gold-bearing quartz veinlets and quartz stockworks.The authors selected hydrothermal zircon in the gold-bearing quartz vein for metallogenic epoch research.Some of the zircons were corroded with no rings or weak rings.These zircons also have high Th, U, Pb content and Th/U ratios, indicating that these zircons are hydrothermal zircons.LA-ICP-MS U-Pb analysis of these zircons yielded a concordant age of 110±7 Ma, which is contemporaneous with the continental napping event in this area in late Early Cretaceous, which should be an important metallogenic epoch of the gold deposit.The authors hold that a tectonic altered rock type gold mineralization occurred in Late Yanshanian period in the Chaijiazhuang gold concentration area, which was related to the contemporaneous large-scale tectonic movement.
