Geological characteristics and metallogenic epochs of the Dapai Fe-Pb-Zn polymetallic deposit in Yongding County, Fujian Province
-
Abstract
The Dapai Fe-Pb-Zn polymetallic ore deposit in Yongding County of southwestern Fujian Province is a large-sized polymetallic deposit discovered in recent years. Zircon SHRIMP U-Pb dating of Dapai altered granodiorite is (127±1.8) Ma, equal to the Re-Os isotopic age (133.5±4.1) Ma of the granodiorite porphyry. Both ages are consistent with the age of Makeng and Pantian iron ore deposit in the same area, indicating genetic relation between the granitic magmatism and the Fe-Pb-Zn metallogenesis in the area, with the main metallogenic epoch being Yanshanian. Based on the previous research results and data obtained by the authors, it is inferred that the Dapai Fe-Pb-Zn polymetallic ore deposit belongs to stratabound skarn-porphyry type composite deposit. -
