1. Introduction In many parts of the world, the technique of electrical sounding has been used effectively for solving subsurface water problems in order to minimize drilling costs (e.g. Breusse 1963; Zohdy and Jackson, 1969; Zohdy, 1969; Zohdy et. al. 1984). During June 1999, resistivity surveys was made at the western Amman basin to provide some information about the thickness, lithology and tectonics of the subsurface layers and then to locate suitable drilling sites for water wells.

1. Introduction Kurgan, a frontier station in the south foot of the Southwest Tianshan Mountains, is located on the NW margin of the Tarim Basin (Fig. 1). The Mesozoic coal-bearing molasses there is the most west Mesozoic outcrop of the Kuqa Depression, a tectonic unit of Tarim and its adjacent area. It is very difficult for geologist to access there. This results in the lack of geological works in this area. Meanwhile, only a few petroleum exploration works have been accomplished in t… 相似文献

As an important tectono-stratigraphic unit on the northwestern margin of the North China Plate, the Zhartaishan Group of Mid-Proterozoic age is widely exposed in the Langshan-Zhartaishan area, Inner Mongolia (Fig. 1). The underlying basement of it is metamorphic rock series of the Upper Archaean Wulashan Group and the Lower Proterozoic Sertengshan Group. The overlying strata are of Paleozoic, Mesozoic and Cenozoic. The Zhartaishan Group is quite different both from the underlying met… 相似文献

The Wahongshan fault zone in Qinghai province is one of the most important faults in westem China. In this paper, deformation and X-ray petrofabrics have been studied in the middle segment of the fault. The results show that the formation of the fault zones can be divided into two major stages: ductile shear deformation stage and brittle deformation stage. The early stage ductile shearing leads to the formation of the NW-NNW trending mylonite zones along the fault, which is intensely cut by the late-formed brittle faults. X-ray petrofabrics of rocks near the faults indicate that the minerals in the tectonites show a great degree of orientation in the alignment. The quartz, which is a very important mineral in the tectonites, is deformed by basal face gliding or near basal face gliding, and sometimes by prismatic face sliding, which indicates that the rocks are deformed in epithermal to mesothermal or mesothermal environment, and the dynamic recrystallization also plays an important role in the formation 相似文献

The Qiangtang basin is located between Kekexili-Jingshajiang suture belt and Bangong-Lujiang suture belt, and is divided into the north part and south part by the central uplift that has no crop out of Mesozoic strata. When the Jinshajiang Ocean was closed, the subducting plate was subducted southward. In the central part of the Qiangtang basin, the cushioning effect of the asthenosphere resulted in the thermal doming of the mantle and subsequent large-scale anatexis. Mantle source materials and antectic materials were upwelled and extruded into the middle crust, leading to the thickening of the middle crust and the heating and weakening of the middle to upper crust, and resulting in the rapid deformation (detachment) and tectonic erosion, and in the isostatic uplifting and the formation of metamorphic core complex. The upwelling of anatectic materials would further enhance the buoyant repercussion, which would combine with the side stress due from extrusion in resulting in the formation of an extension 相似文献

The gas in a petroleum pool varies in direct proportion to the concentration of higher methane compounds. This fact,' and strongly characteristic butane‐isobutane and pentane‐isopentane ratios resulting from petroleum reservoirs chemistry, seems to serve as a reliable standard for distinguishing between pools in the Oligocene‐Miocene and Pliocene reservoirs of the Azerbaydzhan (West Caspian) basin. ‐‐M.

It is quite generally accepted that the growth of the Pleistocene ice-capsdemanded world-wide depression of mean sea-level; indeed,as Henri Bauligsays,"it expresses a physical necessity." There is striking evidence,moreover,for such a recent depression in the extension of river systems across the continental 相似文献
