Summary:Basement structures exposed at the margins of the Junggar Basin were created during the Altaid orogeny in the late Palaeozoic; they were reactivated by Mesozoic-Cainozoic compressional events, which were the long-distance expression of orogenies at the S margin of Asia. Cainozoic strain was partitioned between strike-slip motion on basement structures within the Palaeozoic orogenic belts around the Junggar Basin, and numerous thrusts and transpressive faults in regions marginal to and within the basin itself. Most major strike-slip faults are reactivated structures, and occupy narrower zones than their Palaeozoic precursors. Thrust zones follow the Palaeozoic basement grain, but active faults have propagated into the Mesozoic-Cainozoic cover. [R.A.H.]
