Geology of the Fuding inlier in southeastern China: Implication for late Paleozoic Cathaysian paleogeography

Provenance analysis of the Miocene accretionary prism of the Hengchun Peninsula, southern Taiwan, and regional geological significance

“…The age relative probability of detrital zircons was processed using Isoplot (Version 3.23) (Ludwig, 2000(Ludwig, , 2003. For statistical purposes, zircon ages with discordance <10% are considered as to be valid (Hu et al, 2012a), therefore zircon ages with discordance >10% were deleted, by which more than 53 valid data were obtained for each study sample (Data Repository) for further analyses. Usually, detrital zircon U-Pb dating needs more than 100 grains to get good enough statistics (Vermeesch, 2004).…”

“…9). The Wuyishan terrane is characterized by dominant Paleoproterozoic (approximately 1.86 Ga) and lesser Neoarchean basement (Hu et al, 2012a). All these sediments could be the 'recycled orogen' sediment source area.…”

Phanerozoic tectonics of the South China Block: Key observations and controversies

“…Data source is same as that in Fig. 6b. (2011) and Hu et al (2012) claimed that they have identified a magmatic arc of ca. 260-280 Ma along Southeast China based on the U-Pb age spectra and Hf-O isotopic compositions of detrital zircons in the upper Permian sediments.…”

Late Paleozoic magmatism in South China: Oceanic subduction or intracontinental orogeny?

“…Hu et al [24] proposed that the detrital zircons probably originated from the northeastern Cathaysia Block and recorded the late Paleozoic magmatism in the continental rifting setting. However, the lack of direct geochemical and isotope evidence of protolith hampers them to exclude an alternative scenario that the late Paleozoic magmatism occurred in the continental arc environment related to the oceanic subduction.…”

“…They related it to the amalgamation of the SCB with the Indochina-South China Sea plate during the convergence of the late Paleozoic Pangea supercontinent. Recently, 340-280 Ma detrital zircons were found in late Paleozoic sedimentary rocks in the SCB [24,25], stimulating interest in the late Paleozoic tectonics and magmatism. However, the sedimentary provenances of detrital zircons and the nature of their host magma are very difficult to decipher.…”
