The research results can provide basic data for early basin structural study. From coupled basin and mountain system, analysis of the structure, and evolution of Kumkuli basin, we found that there was zoning from north to south and from west to east. Kumkuli basin has three structural architecture layers including metamorphic crystallization basement, fold basement and sedimentary cover. Kumkuli basin can be divided into three structural units, two depressions, and one uplift. Structural evolution of the Kumkuli basin can be divided into five evolution stages, including Kumkuli microcontinent formed in Sinian-Ordovician, suture around Kumkuli basin formed in Eopaleozoic, retroare foreland basin formed in Neopaleozoic, rejuvenated foreland ba-sin developed in Mesozoic, and strike slip and compression basin developed in Cenozoic.展开更多
