Identification of Baihesi aluminous A-type granite: Magmatic response to the onset of Cretaceous extension in eastern Jiangnan Massif, South China
Published 2023-02-01“…The εHf(t) values of Baihesi granite range from −5.57 to −2.37, with two-stage model ages (TDM2) ranging from 1,551 to 1,345 Ma, suggesting a similar source to Neoproterozoic arc-related magmatic rocks in the Shuangqiaoshan Group. We argue that Baihesi granite has originated mainly from partial melting of a reworked juvenile crust related to Neoproterozoic arc-related magmatism in the Jiangnan Massif, which was controlled by subduction along the South China active continental margin. …”
