西昆仑山前东段新生代褶皱冲断带及其锥形楔机制
Cenozoic fold and thrust belt in eastern section of the piedmount of west Kunlun and its taper wedge mechanics
摘要
Abstract
Hetian-Kekeya structural belt is away from Mazartagh structural belt in Tarin Basin about 200 km,they are almost parallel. Mazartagh structural belt is leading edge of Hetian-Kekeya structural belt, the Cenozoic compressive deformation of Hetian-Kekeya along the gypsum -mudstone of Aertashi Formation slide to Mazartagh and transformed to Fault-propagation-folds, leaded obvious topographic rise in Tarim Basin. So,the Cenozoic fold and thrust belt in eastern section of the piedmount of west Kunlun is 270 km in width and 220 km in length, it consisted of Hetian-Kekeya structural belt, Maigaiti slope and Mazartagh structural belt. Maigaiti slope is almost 200 km in length, but it hasn't obvious deformation, and taper wedge angle of this fold and thrust belt is less than those active orogenies, it's means the gypsum-mudstone of Aertashi Formation and the shape of Cenozoic deposition are key factors, the gypsum-mudstone controls a of taper wedge,the shapes of basement and dispositive wedge control β of taper wedge.关键词
