Abstract
The Dajishan deposit is a well-known tungsten and niobium-tantalum deposit in China. Due to the technological restrictions, little work has been done on the ages of ore-forming and related granite in Dajishan for a long time. By means of the single-zircon U-Pb isotopic method, the intrusion age is reported in this paper, which is (151.7±1.6) Ma for a patched granite body (the source granite for Nb-Ta). By quick neutron mobilization method, an 40Ar-39Ar age of mica from the major ore vein is determined, yielding ore-forming ages of 144 Ma and 147 Ma. Combining these age data with the occurrences of the main granite body, the patched body, the major ore veins and Na-Ta mineralization, the paper discusses their formation orders and relationships. These data also show that the Dajishan granite and its related mineralizations are the product of magmatism in the middle Yanshanian stage and a part of the secondary large-scale mineralization in the Mesozoic.
