Petrography and geochemistry of lower carboniferous greywacke and mudstones in Northeast Junggar, China: Implications for provenance, source weathering, and tectonic setting.

Highlights: [•] Petrography and geochemistry data are applied in this research. [•] The Dulate arc is the primary source area. [•] REE mixing of provenance modelling method is used to determine the source rocks. [•] The sedimentary rocks deposit in a back-arc basin. [•] The back-arc basin formed by the southward subduction of the Zaysan–Erqis Ocean. [Copyright &y& Elsevier]
