Early Paleoproterozoic (ca. 2.36 Ga) post-collisional granitoids in Yunnan, SW China: Implications for linkage between Yangtze and Laurentia in the Columbia supercontinent

•We present the rarely reported early Paleoproterozoic magmatic records in the Yangtze Block.•The ca. 2.36 Ga Cuoke monzogranites formed within post-collisional setting.•They were likely derived from a source comprising mainly Mesoarchean crustal materials.•The SW Yangtze Block likely underwent a collision event related to the Arrowsmith orogeny.•A spatial connection between Yangtze and Laurentia in the Columbia supercontinent is favored.
