Early Neoproterozoic (∼840 Ma) slab window in South China: Key magmatic records in the Chencai Complex

It has been generally accepted that the Neoproterozoic amalgamation of the Yangtze and Cathaysia Blocks along the Jiangnan orogenic zone created the united South China Block (SCB). However, its final oceanic consumption time and subsequent assemblage process remain controversial. This paper presents a set of new geochronological, geochemical and Sr-Nd-Hf-O isotopic data for the early Neoproterozoic mafic to felsic igneous rocks in the...
