I-type granitoids associated with the early Paleozoic intracontinental orogenic collapse along pre-existing block boundary in South China

The early Paleozoic Wuyi–Yunkai orogeny resulted in extensive magmatism in the Cathaysia and eastern Yangtze blocks, South China. Identifying the nature of related magmatism is essential for understanding the orogeny that remains enigmatic with regard to its tectonic setting and geodynamic driving force. The Zhangjiafang pluton (438 ± 3 Ma) in western Jiangxi province is composed of predominant granodiorite with abundant coeval...
