Lower Palaeozoic

The Late Precambrian and early Palaeozoic marginal basin of South China

An integrated study based on recent geological mapping and encompassing the evolution of sedimentary facies, volcanism, plutonism and metamorphism in the Sinian and early Palaeozoic rocks of SE China has led to a reinterpretation of the area as representing a marginal basin situated at the SE margin of the Yangtze continental plate. The marginal basin comprised an active basin or trough and an inactive or marginal sea. The two parts display different sedimentary facies and tectonic and volcanic histories. It is concluded that in the early stages of evolution magma was derived from the mantle but later magmas were generated mainly in the crust.
