Carbonated sediment recycling and its contribution to lithospheric refertilization under the northern North China Craton

Fig. 1. Simplified tectonic map of the North China Craton (modified from Zhao et al., 2001). WB =Western block, TNCO =Trans‑North China orogen, and EB= Eastern block. Blue diamonds represent the locations of the presence of high 87Sr/86Sr peridotites
in the northern North China Craton (Wang et al., 2016; Xu et al., 2003; Zhang et al., 2009, 2012). Green circles represent the locations of the previously reported high 87Sr/86Sr carbonatites in the northern North China Craton (Chen et al., 2016; Liu et al., 2015; Yan
et al., 2007). (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
