Abstract
The Chinese Tianshan belt is a major part of the southern Central Asian Orogenic Belt extending westward to Kyrgyzstan and Kazakhstan Its Paleozoic tectonic evolution crucial for understanding the amalgamation of Central Asia comprises two stages of subductioncollision The first collisional stage built the EoTianshan Mountains before a Visean unconformity in which all structures are verging north It implied a southward subduction of the Central Tianshan Ocean beneath the Tarim active margin that induced the OrdovicianEarly Devonian Central Tianshan arc to the south of which the South Tianshan backarc basin opened During the Late Devonian the closure of this ocean led to a collision between Central Tianshan arc and the KazakhstanYiliNorth Tianshan Block and subsequently closure of the South Tianhan backarc basin producing two suture zones namely the Central Tianshan and South Tianshan suture zones where ophiolitic mélanges and HP metamorphic rocks were emplaced northward The second stage included the Late DevonianCarboniferous southward subduction of North Tianshan Ocean beneath the EoTianshan active margin underlined by the YiliNorth Tianshan arc leading to the collision between the KazakhstanYiliNTS plate and an inferred Junggar Block at Late CarboniferousEarly Permian time The North Tianshan Suture Zone underlines likely the last oceanic closure of Central Asia Orogenic Belt all the oceanic domains were consumed before the Middle Permian The amalgamated units were affected by a Permian major wrenching dextral in the Tianshan The correlation with the Kazakh and Kyrgyz Tianshan is clarified The Kyrgyz South Tianshan is equivalent to the whole part of Chinese Tianshan CTS and STS located to the south of Narat Fault and Main Tianshan Shear Zone the socalled Middle Tianshan thins out toward the east The South Tianshan Suture of Kyrgyzstan correlates with the Central Tianshan Suture of Chinese Tianshan The evolution of this southern domain remains similar from east Gangou area to west until the TalasFerghana Fault which reflects the convergence history between the Kazakhstan and Tarim blocks
