“…The southern edge of the basin was slightly uplifted and migrated northward to approximately its presentday position (Fang et al, 2006). The clockwise rotation of the Junggar block continued and intra-basin highs, which initiated during the Jurassic, reached their climax in Early Cretaceous with relative topographies up to 600 m based on erosion surfaces imaged by seismic data (Hou et al, 2009). A similar basin margin uplift is observed in the north Tarim Basin margin.…”

“…3c). Small-scale tectonic activity, driven by a Jurassic -Early Cretaceous clockwise rotation of the Junggar block (Hou et al, 2009) is also observed in the northern and western Junggar during the Early and Middle Jurassic, both on thrust faults (Allen and Vincent, 1997) and normal faults (Liu et al, 2006). Seismic data interpretation indicates that this tectonic activity induced the uplift of topographic highs in the basin that propagated from south to north.…”

Abstract. The topographic evolution of continents and especially the growth and dismembering of mountain ranges plays a major role in the tectonic evolution of orogenic systems, as well as in regional or global climate changes. A large number of studies have concentrated on the description, quantification and dating of relief building in active mountain ranges. However, deciphering the topographic evolution of a continental area submitted to recurrent tectonic deformation over several hundred millions of years remains a challenge. Here we present a synthesis of the tectonic, geochronological and sedimentological data available on the intracontinental Tian Shan Range to describe its general topographic evolution from Late Palaeozoic to Early Tertiary. We show that this evolution has occurred in two very distinct geodynamic settings, initiating during the Carboniferous in an ocean subduction -continent collision tectonic context before becoming, from Early Permian, purely intra-continental. We show that during most of the Mesozoic, the topography is mostly characterized by a progressive general decrease of the relief. Nonetheless localized, recurrent deformation induced the formation of small-scale reliefs during that period. These deformations were driven by far field effects of possibly several geodynamic processes in a way that still remains to be fully understood.

Mesozoic basins in northwest China provide important records for investigating relationships between intraplate deformation in Central Asia and tectonic processes at Asian boundaries. The present study, using well, seismic, outcrop, and thermochronology data in the Junggar Basin and neighboring areas, describes the main features of Jurassic strata in the basin, analyzes the Jurassic evolution of the basin and neighboring mountain belts, and discusses possible mechanisms of Jurassic intraplate deformation in Central Asia. During the Early-Middle Jurassic, episodic uplift of surrounding mountain belts kept the Junggar Basin a contractional closed basin, and alluvial fan, fluvial, delta, and lacustrine depositional environments successively developed from surrounding ranges to the central basin. During the Late Jurassic, the western and central parts of the basin were folded and uplifted, and deposition migrated mainly to the eastern basin. During the latest Jurassic-earliest Cretaceous, pre-Cretaceous strata in the eastern and northeastern Junggar Basin were folded and uplifted, and coarse-grained sediments were transported from surrounding uplifts to the central basin. We suggest that Jurassic episodic deformation events in the Junggar Basin and other areas of Central Asia are related to the Qiangtang collision during the Late Triassic-Early Jurassic, the closure of the western Mongol-Okhotsk Ocean at the Early/Middle Jurassic boundary, a collision of a microcontinent in the Pamir with the southern Asian margin during the late Middle Jurassic-early Late Jurassic, the collision of the Kolyma-Omolon Block with Siberia at the end of the Jurassic, and the subsequent closure of the eastern Mongol-Okhotsk Ocean during the latest Jurassic-earliest Cretaceous.

“…Especially during the Late Jurassic, northwest Junggar, from the Chepaizi to the east Mosuowan, Sangequan, and Dibei, experienced an uplift period (Chemo paleo-uplift) and underwent large-scale erosion, so that the Jurassic sequence is absent on the ancient uplifts. From the Sangonghe Formation (J 1 s) to the Toutunhe Formation (J 2 t), the volumes and areas of denudation increased, reaching a peak value of 40000 km 2 during the Qigu Formation (J 3 q) to the Kalazha Formation (J 3 k) (Hou et al, 2009). The Toutunhe and Qigu formations are conformably and disconformably distributed in the central basin, but unconformably in the heights and along the margin of the basin.…”

Weathered clastic crust can be subdivided into weathered clay and leached zone in terms of variable weathering of different minerals and mobility of weathered products. On the basis of clastic outcrops and well cores in the Junggar Basin, the dark red Fe-rich weathered clay is formed in an arid environment, whereas the light blue Al-rich weathered clay under humid conditions. According to the geochemical analysis, a new weathering index for weathered clastic crust is built mainly on Fe and Al contents, accurately indicating the weathered clay, sandy leached zone, and muddy leached zone in the Junggar Basin. The breaking pressure of weathered clay is rather large, the same as that of normal muddy cap, effectively to seal oil or gas. The porosity of underlying leached zone is greatly enhanced by weathering and leaching, but its permeability is a function of clay mineral content, i.e., the higher the clay content, the worse the permeability. Weathered crust provides effective sealing conditions for both top and bottom layers of a petroleum reservoir, and is important in the clastic hydrocarbon exploration. structure of weathered crust, weathering index, Junggar Basin, reservoir properties, hydrocarbon exploration Citation: Zou C N, Hou L H, Yang F, et al. 2014.
