英文摘要: Abstract(#br)The Mesozoic Shanghang Basin in southeastern China consists of Early Cretaceous mottled coarse-grained clastic and volcanic rocks, and Late Cretaceous clastic rocks. The volcanic rocks are intermediate-mafic to felsic and spatially close to the famous Zijinshan Mineral Field. In order to better understand the timing, petrogenesis and tectonic setting of these volcanic rocks and the relationship between magmatism and metallogeny in the mineral field, U–Pb zircon geochronological, geochemical and Sr–Nd–Pb–Hf isotopic studies were completed on the volcanic rocks. Fifteen LA-MC-ICP-MS U–Pb zircon analyses of the volcanic rocks yield weighted mean ages of between 105 and 99Ma. Major and trace element geochemistry shows that these rocks are mostly high-K to...
