Abstract

Abstract

The Xuwu subdacitic porphyry is located in the south of the Dabaoshan ore district. This paper reports for the first time the SHRIMP zircon U-Pb age of Xuwu dacitic porphyry (441.2±4.2Ma), suggesting Caledonian. Combined with the previous dating results, the authors conclude that there are two rock-forming stages (Caledonian and Yanshanian) and one ore-forming stage (Yanshanian) in the Dabaoshan ore district, with the mineralization mainly related to the Yanshanian intrusions.
