Abstract We use detrital provenance data from Cambrian sandstones to examine whether the Yangtze and Cathaysia blocks in South China were separated by an ocean during the Cambrian period. Zircons from the Cambrian sandstones exhibit a dominant ~ 800 Ma age peak in the central Yangtze Block, being sourced from the western Yangtze Block, whereas a ~ 980 Ma peak dominates in the northwestern Cathaysia Block, being sourced from an exotic continent once connected to Cathaysia. A mixed provenance… Expand
The nature of Early Palaeozoic Kwangsian orogenic event in the South China Block: constraints from detrital zircons in Cambrian strata
ABSTRACT The tectonic nature of Early Palaeozoic Kwangsian orogeny in the South China Block (SCB) is still debated, due to controversy whether there was a Cambrian ocean between the Yangtze Block andExpand

Abstract South China is the largest block of Rodinia in southeastern Asia. It consists of the Yangtze and Cathaysia blocks, separated by the Jiangshan-Shaoxing-Pingxiang Fault. Most studies suggestExpand
Late Paleozoic to Early Mesozoic provenance record of Paleo‐Pacific subduction beneath South China
Northeast trending Yong'an Basin, southeast South China Craton, preserves a Permian-Jurassic, marine to continental, siliciclastic-dominated, retroarc foreland basin succession. Modal and detritalExpand
Provenance, depositional setting, and crustal evolution of the Cathaysia Block, South China: Insights from detrital zircon U–Pb geochronology and geochemistry of clastic rocks
We report the results of a combined study of detrital zircon U–Pb geochronology and bulk‐rock elemental geochemistry on late Neoproterozoic to Cambrian clastic sedimentary rocks from South JiangxiExpand
The provenance and tectonic setting of the Lower Devonian sandstone of the Danlin Formation in southeast Yangtze Plate, with implications for the Wuyi-Yunkai orogeny in South China Block
Abstract The South China Block was subject to widespread tectonic and magmatic events during the middle Ordovician to earliest Devonian which are collectively called the Wuyi-Yunkai orogeny. TwoExpand
U–Pb ages and Hf isotopes of detrital zircons from pre-Devonian sequences along the southeast Yangtze: a link to the final assembly of East Gondwana
Abstract The Early Palaeozoic geology of the South China Craton (SCC) is characterized by an Early Palaeozoic intracontinental orogen with folded pre-Devonian strata and migmatites, MP/MT metamorphicExpand
Provenance and depositional setting of Lower Silurian siliciclastic rocks on Hainan Island, South China: Implications for a passive margin environment of South China in Gondwana
Abstract Diverse models have been proposed for interpreting the early Paleozoic tectonic setting of the Cathaysia Block in South China. However, few of them undertook a comprehensive study of clasticExpand
Middle Jurassic collision of an exotic microcontinental fragment: Implications for magmatism across the Southeast China continental margin
Abstract Thrusting, folding, and metamorphism of late Paleozoic to middle Mesozoic sedimentary rocks, together with high precision U–Pb zircon ages from Middle to Late Jurassic volcanic and graniticExpand
The Trace Element Characteristics of Shales from Upper Ordovician-Lower Silurian in Wuling Depression: Implication for Block Amalgamation Time and Tectonic Setting
The collision time of the Yangtze Block and the Cathaysia Block has been controversial for decades. This paper discusses the sedimentary provenance and tectonic setting through the analysis of theExpand
Spatiotemporal evolution and causes of marine euxinia in the early Cambrian Nanhua Basin (South China)
Abstract Marine redox conditions and their dynamic variations in the early Cambrian are thought to have strongly influenced the evolution of early animals. However, the patterns and mechanisms ofExpand


South China in Rodinia: Part of the missing link between Australia–East Antarctica and Laurentia?
Stratigraphic correlations and tectonic analysis suggest that the Yangtze block of South China could have been a continental fragment caught between the Australian craton and Laurentia during theExpand
From Rodinia to Gondwanaland: A tale of detrital zircon provenance analyses from the southern Nanhua Basin, South China
The paleogeographic positions of the South China Block (SCB) during the Neoproterozoic and early Paleozoic are important for understanding the transition from the break-up of the supercontinentExpand

Tectonics of South China: Key to understanding West Pacific geology
Abstract South China is not a post-Caledonian platform, but a composite of orogenic belts. This late Proterozoic/Mesozoic orogen is a collage of three continental fragments. The three blocks areExpand
Amalgamation between the Yangtze and Cathaysia Blocks in South China: Constraints from SHRIMP U–Pb zircon ages, geochemistry and Nd–Hf isotopes of the Shuangxiwu volcanic rocks
Abstract South China was formed through the amalgamation of the Yangtze Block with the Cathaysia Block, but the timing of this amalgamation is controversial, ranging from Mesoproterozoic to Mesozoic.Expand
