The North China Craton (NCC) is one of the oldest cratonic blocks in the world as old as 4.0 Ga (Wan et al., 2021), which is bounded by the Central Asian Orogenic Belt to the north and the Qinling-Dabie and Sulu Orogenic belts to the south (Fig. 1 a) (Liu et al., 2008, Wu et al., 2008, Zhai and Santosh, 2011, Zhai, 2014).There is a broad consensus that the NCC was …

A number of Late Mesozoic (∼130 Ma) A-type granitic plutons have been identified in Southeast China.Here we investigate the petrogenesis of one of these granitic plutons in Southeast China, the Sanqingshan–Damaoshan (SD) granites in northeastern Jiangxi Province, using zircon U–Pb geochronology, Hf isotopic analyses, and major and trace element analyses.

We have identified a new crustally derived granite pluton that is related to the Emeishan Large Igneous Province (ELIP). This pluton (the Wase pluton, near Dali) shows two distinct SHRIMP zircon U–Pb age groups (~768 and ~253 Ma). As it has an intrusive relationship with Devonian limestone, the younger age is interpreted as its formation, which is related to …

The geochemical comparation shows that the South China granites share similar REE contents with those of many granites from places outside South China. Such similarity has also been found between REE ore-related and ore-barren granites in South China. This shows that granites from outside South China could also have ore-forming potential.

The 2.31 Ga Low δ 18 O granites were related to partial melting of high-T hydrothermal altered crustal rocks in a rift.. The weaker low-18 O signatures of the 2.18 Ga granites were inherited from the 2.31 Ga granites.The southern TNCO went through tectonic switch from continental rift to active continental margin during 2.3–2.1 Ga.

India and China are two big players in the international natural stone market. Both countries produce granite in multiple colors and finishes. In Eastern China, places like Guangdong, Fujian, and Shandong are known for quarrying granite in bulk. Like China, India also has lots of quarries and processing units in Chennai, Bangalore, and Rajasthan.
