根据华南地区新元古代火成岩及其相关岩石（包括蛇绿岩、弧火山岩和侵入岩以及随后的双峰岩浆作用）的时空分布，确定了扬子地块和华夏地块之间存在新元古代洋内弧、大陆-弧-大陆碰撞和3个构造-岩浆带。揭示了扬子地块与华夏地块的融合和构造-岩浆史：在~ 1000 ~ 860 Ma，西北洋-洋俯冲和东南洋-陆俯冲分别导致华夏地块洋内弧岩浆活动和大陆边缘岩浆活动。在~ 860 ~ 825 Ma，洋内弧带陡坡俯冲导致弧后盆地发育，板块回滚诱发华夏地块弧后岩浆活动。与此同时，一次浅倾的西北洋陆俯冲在扬子地块形成了活跃的大陆边缘岩浆活动。在~ 825-805 Ma，扬子地块和华夏地块之间的大陆-弧-大陆碰撞和最终合并产生了江南造山带。~ 805 ~ 750 Ma，江南造山带崩塌，形成南华裂谷盆地。我们的研究还排除了华南任何格伦维利亚造山事件和地幔柱活动，并表明华南在罗丁尼亚超大陆中处于边缘位置。
According to the temporal-spatial distribution of Neoproterozoic igneous rocks and relative rocks in South China, including ophiolites, arc volcanic and intrusive rocks and subsequent bimodal magmatism, we identified the presence of a Neoproterozoic intra-oceanic arc, continent-arc-continent collision and three tectono-magmatic zones between the Yangtze Block and Cathaysia Block. We have also unraveled the amalgamation and tectono-magmatic histories between the Yangtze and Cathaysia blocks: At ∼1000–860 Ma, northwestward ocean-ocean subduction and southeastward ocean-continent subduction resulted in the intra-oceanic arc magmatism and active continental margin magmatism in the Cathaysia Block respectively. At ∼860–825 Ma, the steepening subduction caused development of back-arc basin in the intra-oceanic arc zone and the slab rollback induced the arc and back-arc magmatism in the Cathaysia Block. Meanwhile, a shallow dip northwestward ocean-continent subduction formed active continental margin magmatism in the Yangtze Block. At ∼825–805 Ma, the continent-arc-continent collision and final amalgamation between the Yangtze and Cathaysia blocks yielded the Jiangnan Orogen. At ∼805–750 Ma, the Jiangnan Orogen collapsed, and the Nanhua rift basin formed. Our study also rules out any Grenvillian Orogenic event and mantle plume activity in South China and indicates a marginal position of South China in the Rodinia supercontinent.
