英文摘要Late Permian to Triassic ("Indosinian-aged") orogenesis and associated magmatism are widespread in southeastern China, but their causes and significance to the regional geodynamic evolution are highly controversial. We report in this study integrated in situ U-Pb, Hf and O isotope analyses of detrital zircons from the Middle to Late Permian sediments in southeastern China, and use these data to decipher the sedimentary provenances, regional magmatic barcode and crustal evolution processes. A total of 409 concordant U-Pb zircon analyses on five sedimentary samples exhibits four major age peaks at ca 1870 Ma, ca 445 Ma, ca 370 Ma and ca 280 Ma, one "broad" age group of ca 1180-960 Ma, and two subordinate peaks at ca 2530 Ma and ca 800 Ma All the Archean-aged detrital zircons are oval in shape with clear abrasive imprints, indicating long-distance transport and/or multi-cycled sedimentary processing from unknown Archean sources. In contrast, detrital zircons of the remaining age groups are mostly euhedral to subhedral crystals, suggesting short-distance transport. Zircon ages of ca 1870 Ma, ca 1180-960 Ma, ca 800 Ma, ca 445 Ma and ca 280 Ma are coeval with exposed magmatic rocks in the Cathaysia Block of southeastern China. The ubiquitous existence of ca 280 Ma detrital zircons in the studied sediments implies a widespread occurrence of Early Permian magmatic rocks in southeastern China coastal region.
