2020-5-26 · It is proposed that the Neoproterozoic bimodal volcanic suites from the Dingyuan and the Qijiaoshan formations are erupted coevally, but have different sources and magmatic processes. The bimodal volcanic rocks in this study provide evidences for an enriched lithospheric mantle beneath the Dabie terrain at ca.740 Ma, and a rifting extensional setting for the north margin of the Yangtze block.
