“…Detrital zircons with the age cluster of 1700-1200 Ma are widely reported for (meta)sedimentary rocks in both the Yangtze and the Cathaysia Blocks of South China ( Fig. 9b and c; Li et al, 2007;Greentree et al, 2006;Wang et al, 2007aWang et al, , 2010bWang et al, , 2012aWang et al, , 2013bWang et al, , 2014aYu et al, 2008Yu et al, , 2010Sun et al, 2009;Zhou et al, 2009;Wan et al, 2010;Wu et al, 2010;Duan et al, 2011;Yao et al, 2011Yao et al, , 2012Xu et al, 2012;Cawood et al, 2013b).

The only reports include the Grenvillian metamorphism along the SE and the northern to western margins of the Yangtze (e.g., Li et al, 1995Li et al, , 2002Li et al, , 2007Qiu et al, 2000;Wang et al, 2010bWang et al, , 2012a, and the minor ca. 1100-900 Ma igneous rocks on the western and SE margins of the Yangtze (e.g., Li et al, 2002Li et al, , 2009aGreentree et al, 2006;Sun et al, 2009).…”

“…In addition, these workers also argued that the Yangtze and Cathaysia blocks amalgamated to form the coherent South China Block during the Sibao orogenesis at c. 1.1-0.9 Ga (e.g. Li et al 2002bLi et al , 2006Li et al , 2007cGreentree et al 2006;Ye et al 2007), thus precluding the occurrence of any 860-740 Ma magmatic arc in the interior of the South China Block.…”

“…The outcrop is a small (about 300 km 2 ) but well-preserved Neoproterozoic volcanisedimentary succession . Volcanic rocks occur at the bottom of the basin that overlies on the Mesoproterozoic Tianli Schists (Li et al 2007c) with a high-angle unconformity. Therefore, they were formed after the Sibaoan orogenesis.…”

-Middle Neoproterozoic igneous rocks are widespread in South China, but their petrogenesis and tectonic implications are still highly controversial. The Guangfeng middle Neoproterozoic volcanisedimentary succession was developed on a rare Sibaoan metamorphic basement (the Tianli Schists) in the southeastern Yangtze Block, South China. This paper reports geochronological, geochemical and Nd isotopic data for the volcanic rocks in this succession. The volcanic rocks consist of alkaline basalts, andesites and peraluminous rhyolites. SHRIMP U-Pb zircon age determinations indicate that they were erupted at 827 ± 14 Ma, coeval with a widespread episode of anorogenic magmatism in South China. Despite showing Nb-Ta depletion relative to La and Th, the alkaline basalts are characterized by highly positive εNd(T) values (+3.1 to +6.0), relatively high TiO 2 and Nb contents and high Zr/Y and super-chondritic Nb/Ta ratios, suggesting their derivation from a slab melt-metasomatized subcontinental lithospheric mantle source in an intracontinental rifting setting. The andesites have significantly negative εNd(T) values (−9.3 to −11.1) and a wide range of SiO 2 contents (57.6-65.6 %). They were likely generated by the mixing of fractionated basaltic melts with felsic melts derived from the Archaean metasedimentary rocks in the middle to lower crust. The rhyolites are highly siliceous and peraluminous. They are characterized by depletion in Nb, Ta, Sr, P and Ti and relatively high εNd(T) values (−3.0 to −4.8), broadly similar to those of the adjacent c. 820 Ma peraluminous granitoids derived from the Mesoproterozoic to earliest Neoproterozoic sedimentary source at relatively shallow levels. We conclude that the Guangfeng volcanic suite is a magmatic response of variant levels of continental lithosphere (including lithospheric mantle and the lower-middle to upper crust) to the middle Neoproterozoic intracontinental rifting possibly caused by mantle plume activity.

Northeast trending Yong'an Basin, southeast South China Craton, preserves a Permian-Jurassic, marine to continental, siliciclastic-dominated, retroarc foreland basin succession. Modal and detrital zircon data, along with published paleocurrent data, sedimentary facies, and euhedral to subhedral detrital zircon shapes, indicate derivation from multicomponent, nearby sources with input from both the interior of the craton to the northwest and from an inferred arc accretionary complex to the southeast. The detrital zircon U-Pb age spectra range in age from Archean to early Mesozoic, with major age groups at 2000-1700 Ma, 1200-900 Ma, 400-340 Ma, and 300-240 Ma. In addition, Early Jurassic strata include zircon detritus with ages of 200-170 Ma. Regional geological relations suggest that Precambrian and Early Paleozoic detritus was derived from the inland Wuyi Mountain region and Yunkai Massif of the South China Craton. Sources for Middle Paleozoic to early Mesozoic detrital zircons include input from beyond the currently exposed China mainland. Paleogeographic reconstruction in East Asia suggests derivation from an active convergent plate margin along the southeastern rim of the craton that incorporated part of Southwest Japan and is related to the subduction of the Paleo-Pacific Ocean. Integration of the geologic and provenance records of the Yong'an Basin with the time equivalent Yongjiang and Shiwandashan basins that lie to the southwest and south, respectively, provides an integrated record of the subduction of the Paleo-Pacific Ocean along the southeast margin of the South China Craton and termination of subduction of the Paleo-Tethys beneath its southwest margin in Permo-Triassic.
