“…In continental basins, long term tectonic movement is the key factor for developing slope-break zones, expressed by abrupt changes in depositional slope (e.g., Lin et al, 2001Lin et al, , 2002Wang et al, 2004;Huang et al, 2009;Zhang et al, 2009). Research by Lin et al (2001) on the Bohai Bay basin indicated that the structural slope-break zone constrained changes in accommodation space in the basin, marked the boundaries between different palaeogeomorphological units and sedimentary facies, and played an extremely important role in controlling the sedimentary composition of stratigraphic sequences and the distribution of depositional system tracts and the sand bodies (Lin et al, 2000;Wang et al, 2003;Ren et al, 2004;Feng, 2006;Hou et al, 2010).…”

“…Although many advances in the structural and sedimentary geology of the Mesozoic-Cenozoic basins adjacent to the Tian Shan have been published, and structural relations between the Tarim basin (or Kuqa subbasin) and Tian Shan had been approximately outlined (e.g. Graham et al, 1988Graham et al, , 1993Hendrix et al, 1992;Hendrix, 2000;Jia, 1997;Jia et al, 2001;Sobel, 1999;Lu et al, 2000;Gu, 1996;Lin et al, 2002), the geodynamic relations that existed between Tian Shan orogenesis and Kuqa subbasin formational evolution are still ambiguous. This results, at least in part, from both the complexity of tectonic units in the Tian Shan orogenic belt, composed of collages of diverse accreted terranes, and the relative paucity of information about the depositional processes in the Mesozoic-Cenozoic Kuqa subbasin.…”

“…This makes volcanic stratigraphic reservoirs an important research field in oil and gas exploration in China. Above the unconformity, hydrocarbon distribution and accumulation mechanisms of clastic rock strata deposited in sequences have been well studied [4][5][6]. Volcanic hydrocarbon reservoirs found both in China and overseas are mostly located in original Meso-Cenozoic volcanic rocks, and the reservoirs are controlled by lithology and lithofacies [7][8][9][10][11][12].…”

The Upper Carboniferous in northern Xinjiang, China was formed in a post-collisional depression and collapsed structural setting. Within the Upper Carboniferous, volcanic rocks and source rocks alternate over a wide region. At the end of the Carboniferous, these layers were uplifted by plate collisions and subsequently weathered and leached. Volcanic weathering and leaching led to the establishment of weathered crusts that can be divided into five layers. Corrosion and crumble zones in these layers form favorable reservoirs. Volcanic weathering crust formed in sub-aerially exposed paleogeomorphic areas; the five relatively continuous layers are generally preserved in paleogeomorphic lowland and slope regions, but the upper soil layer is usually absent in structurally higher parts of the rock record. The thickness of the weathered layer has a positive nonlinear exponential relationship to the duration of weathering and leaching, and the dynamic equilibrium time of weathered crust is about 36.3 Ma. The thickest weathered layer (~450 m) is located in fracture zones. Weathered crusts are possible from a range of volcanic rocks with different lithologies, given sufficient time for weathering and leaching. The combination of volcanic weathered crust and source rocks results in three types of hydrocarbon accumulation models: (1) sequences of volcanic weathered crust interbedded with source rocks, (2) a quasi-layered weathered volcanic core located above source rocks, and (3) volcanic rocks associated with pectinate unconformities adjacent to source rocks. Each of these three types has the potential to form a giant stratigraphic reservoir of volcanic weathered crust. This knowledge has changed the traditional exploration model of searching for favorable lithologic and lithofacies zones in volcanic rocks, and has changed the viewpoint that the Carboniferous does not have the genetic potential to be the basement of the basin in northern Xinjiang. The concepts developed here are of great scientific significance and application for focusing oil and gas exploration on volcanic weathered crust. As such, the Paleozoic volcanic weathered crust in the midwestern part of China may possibly contain large-scale stratigraphic reservoirs and thus could be a new oil and gas exploration target in the future.
