Abstract
Spilite- keratophyre is a key member of the Shuangxiwu Group volcanic series in Zhejiang Province. Presented in this paper are the reliable Sm- Nd internal isochron age (1012±28 Ma, ЄNd(T)=4.4±0.1) and whole- rock Rb- Sr isochron age (972±40 Ma,ISr=0.70327±8) obtained for the first time by the authors. From the available Nd, Sr and O isotope data in conjunction with the major and trace elements data it is suggested that the Xiqiu spilite- keratophy re is the product of island- arc volcanism during the late Middle Proterozoic.
