Abstract
The Qinling Orogenic Belt is divided commonly by the FengxianTaibai strikeslip shear zone and the Huicheng Basin into the East and West Qinling mountains which show significant geological differences after the Indosinian orogeny The FengxianTaibai fault zone and the MesoCenozoic Huicheng Basin situated at the boundary of the East and West Qinling provide a natural laboratory for tectonic analysis and sedimentological study of intracontinental tectonic evolution of the Qinling Orogenic Belt In order to explain the dynamic development of the Huicheng Basin and elucidate its postorogenic tectonic evolution at the junction of the East and West Qinling we studied the geometry and kinematics of fault zones between the blocks of West Qinling as well as the sedimentary fill history of the Huicheng Basin First we found that after the collisional orogeny in the Late Triassic postorogenic extensional collapse occurred in the Early and Middle Jurassic within the Qinling Orogenic Belt resulting in a series of rift basins Second in the Late Jurassic and Early Cretaceous a NESW compressive stress field caused largescale sinistral strikeslip faults in the Qinling Orogenic Belt causing intracontinental escape tectonics at the junction of the East and West Qinling including eastward finite escape of the East Qinling microplate and southwest lateral escape of the Bikou Terrane Meanwhile the strikesliprelated Early Cretaceous sedimentary basin was formed with a rightorder echelon arrangement in sinistral shear zones along the southern margin of the Huicheng fault Overall during the Mesozoic the Huicheng Basin and surrounding areas experienced four tectonic evolutionary stages including extensional rift basin development in the Early and Middle Jurassic intense compressive uplift in the Late Jurassic formation of a strikeslip extensional basin in the Early Cretaceous and compressive uplift in the Late Cretaceous
