Provenance and origins of a Late Paleozoic accretionary complex within the Khangai–Khentei belt in the Central Asian Orogenic Belt, central Mongolia.

Highlights: [•] Gorkhi Formation clastic rocks were sourced from plutonic rocks in continental margin and continental island arc. [•] The depositional age of the Gorkhi Formation is 340–320Ma. [•] Spatial and temporal changes in the provenance of the accretionary complex are proposed. [ABSTRACT FROM AUTHOR]
