Detrital zircon U–Pb geochronological and Lu–Hf isotopic constraints on the Precambrian magmatic and crustal evolution of the western Yangtze Block, SW China

Detrital zircon U–Pb ages of the Proterozoic metaclastic-sedimentary rocks in Hainan Province of South China: New constraints on the depositional time, source area, and tectonic setting of the Shilu Fe–Co–Cu ore district

“…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). However, rocks with this age range rarely occurred in the South China, except for the metamorphosed volcanic rocks with ages of ca.…”

“…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). Likewise, the Grenville-aged rocks are rarely exposed in the Cathaysia (Fig.…”

“…However, the suggested Grenville-aged orogens in South China are younger by ca. 300-100 Ma even 560-300 Ma (Sun et al, 2009) Li et al (1995Li et al ( , 2002 proposed the ''Missing-Link'' model in which the South China (including Hainan) was located between Australia-East Antarctica and Laurentia. However, Wang et al (2007a) queried on this model due to the selected samples in Li et al (2002) from neither the interior nor areas near the suture between the Yangtze and Cathaysia Blocks, but from Hainan Island.…”

Where was the Ailaoshan Ocean and when did it open: A perspective based on detrital zircon U–Pb age and Hf isotope evidence

“…Hf-isotope evolution line for Depleted Mantle follows Griffin et al (2000). (Greentree et al, 2006;Sun et al, 2009;Duan et al, 2011;Wang et al, 2012;Q.F. Wang et al, 2014).…”

“…Li, 2003;Zhou et al, 2006;Wang et al, 2011;Cai et al, 2014;Qi et al, 2012Qi et al, , 2014. This belt has recently been suggested as a Neoproterozoic arc (i.e., Hannan-Panxi-Yuanjiang arc), comprising Neoproterozoic (Tonian to Cryogenian; 880-720 Ma) arc-related igneous rocks (Zhou et al, 2002b(Zhou et al, , 2006Sun et al, 2008Sun et al, , 2009). Western Yangtze Block had experienced another episode of intense magmatism during the emplacement of the Late Permian (~260 Ma) Emeishan Large Igneous Province (ELIP) (Chung and Jahn, 1995;Shellnutt and Zhou, 2007;Shellnutt et al, 2008;Xu et al, 2008).…”
