Abstract

Abstract

BACKGROUND The Mo-Be deposit in Xiapu Dawan, Fujian Province is located in a volcanic rock area. Mineralization may be closely related to magmatic activity and fracture structure. The concealed granite in the deposit is considered to be the parent rock of Mo-Be ore, but there is no direct time evidence. OBJECTIVES To determine the relationship between albite alkali-feldspar granite and Mo-Be mineralization in this deposit by the geochronology of alkali-feldspar granite. METHODS LA-ICP-MS was used for zircon U-Pb dating of alkali-feldspar granite. RESULTS The results show that the U-Pb age of alkali-feldspar granite is 93.0±0.6 Ma, consistent with that of molybdenum mineralization in this deposit (92.2±1.3 Ma), which indicates that the alkali-feldspar granite is closely related to the mineralization of Mo and Be in time and space. Magmatic activity may provide ore-forming materials and fluids for the Mo-Be ore deposits. CONCLUSIONS The Upper Yanshanian magmatic age and the Mo mineralization age in Fujian Province have the temporal and spatial distribution regularity that becomes gradually younger from west to east. The Mo-Be deposit occurred in the extension of the South China lithosphere during the Yanshanian period.
