英文摘要 | Stratigraphic profiles in the Kuqa subbasin, located along the southern flank or the Tian Shan. northwest China. display similar Mesozoic-Cenozoic evolutionary sequences of compositional maturity exist in conglomerate clasts, sandstone framework grains and detrital heavy minerals. The similarity of these time-series profiles resulted from orogensis and intracontinental deformation of the provenance area, the (ancestral) Tian Shan. Mineralogical maturities of Conglomerates and sandstones increase from Triassic to Middle Jurassic and decrease from Upper Jurassic-Lower Cretaceous to Tertiary. This, trend parallels a similar decrease in maturity in detrital heavy minerals. Zircon. rutile and tourmaline dominate in Middle-Upper Triassic to Middle Jurassic sandstone, whereas unstable hornblende and pyroxene dominate the heavy mineral suites in the Tertiary, especially in Miocene and Pliocene strata. These compositional trends are coeval with gradual southward migration of alluvial depositional fronts and depositional depocenters from Cretaceous to Miocene. Since the Pliocene. lame-scale southward migration of alluvial depositional systems occurred while depositional depocenters migrated northward. |
