Fig. 5: Variation in Sr-Nd isotopes of the late-Mesozoic mafic rocks in west Cathaysia and Jiangnan orogen.

From: Seismically imaged lithospheric delamination and its controls on the Mesozoic Magmatic Province in South China

Fig. 5

The 95–80 Ma mafic rocks along the present coastal area of South China are also plotted for comparison. Sampling locations can be seen in Fig. 1b. a εNd(t)-initial 87Sr/86Sr diagram showing the secular change of Sr-Nd isotopes of the late Mesozoic mafic rocks. b εNd(t)-age variations of the same rocks. The 180–160 Ma mafic rocks occurred along the block convergent boundary (CZF-JSF) and within the Cathaysia block. The areas of DMM (depleted MORB mantle) and N. Yangtze volcanics are from Wang et al.25 for comparison. CZF Chenzhou-Linwu Fault, JSF Jiangshan-Shaoxing Fault.
