U–Pb ages and source composition by Hf-isotope and trace-element analysis of detrital zircons in Permian sandstone and modern sand from southwestern Australia and a review of the paleogeographical and denudational history of the Yilgarn Craton

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

“…The general lack of the igneous rocks and associated metamorphic rocks of typical Grenvillian ages (1300-1000 Ma : Boger et al, 2000) in South China is consistent with the following observations: (1) the Yangtze River system without detrital zircons with a predominant age cluster of 1300-1000 Ma (Yang et al, 2012); and (2) the weak age range of 1300-1000 Ma for detrital zircons from the Precambrian basement members and overlying Neoproterozoic sedimentary strata in the Jiangnan Orogen or the SE margin of Yangtze (Wang et al, 2007a(Wang et al, , 2010b(Wang et al, , 2012b. Therefore, the lack of 1300-1000 Ma magmatism in the South China (Wang et al, 2010b), which is one of the most important events along the continental margins of Australia and Laurentia during the assembly of Rodinia (Veevers et al, 2005;Naipauer et al, 2010 and references therein), rules out the possibility that the 1300-1000 Ma zircons came from the Cathaysia Block. The abundant Mesoproterozoic and especially Stenian (1200-1000 Ma) detrital zircons likely constrain the source rocks of both the Shilu Group and the Shihuiding Formation to be predominantly the 1200-1000 Ma Grenvillian orogeny-related magmatic and metamorphic rocks, such as these in the Grenvillian belts between the eastern Laurentia and its southwestern Amazonia (Fig.…”

Detrital Zircons U-Pb Age and Hf Isotope from the Western Side of the Taiwan Strait: Implications for Sediment Provenance and Crustal Evolution of the Northeast Cathaysia Block

“…This region serves as a canonical area in investigating terrigenous detrital materials transported into the sea, including the provenance and flux, as well as their distribution, transport and dispersion in continental shelves (Liu et al 2002;Dadson et al 2003;Xu et al 2009). Detrital sediments from exposed continental crust across drainage basins may provide a record of the paleogeographic setting and their surrounding source regions (Cawood et al 2003;Veevers et al 2005).…”

“…Therefore, in situ zircon U-Pb dating and Hf-isotope analysis has proven to be a useful tool in assessing the distribution of source rocks in the provenance and reconstructing tectonic evolution of continental blocks (Condie et al 2005;Iizuka et al 2005;Veevers et al 2005;Yang et al 2009;Wang et al 2011). Chen et al (2006) proposed that sediments from the Min River in Fujian, Southeast China, are considered the most likely source of the beach sands of W Taiwan.…”

Middle Jurassic collision of an exotic microcontinental fragment: Implications for magmatism across the Southeast China continental margin

“…2. Kernel density plots (Vermeesch, 2012) of detrital zircon UPb ages of analyzed samples compared with pre-Mesozoic rocks from Cathaysia (Yao et al, 2014;Wang et al, 2015), SE Yangtze (Wang et al, 2013b;Yao et al, 2015), West Australia (Cawood and Nemchin, 2000;Griffin et al, 2004;Veevers et al, 2005), and Western Qiangtang (Zhu et al, 2011;Dong et al, 2011;Pullen et al, 2008;Gehrels, et al, 2011). Differences among these samples are clearly seen on the Multidimensional Scaling (MDS) map (see Fig.…”
