It is believed that three northeast - striking dextral slip fault zones, i. e. the baxian - shulu - handan fault zone, the huanghua - dezhou - dongming fault zone, and the linyi - huanghekou fault zone, are the result of the tectonic transform of paleogene extending to neogene - quaternary laterally slipping of north china plain rift systems, which extend along the central axis of rifts and accord with the quaternary centers of subsidence as the main seismic structures within the rifts

Based on analysis of geologic foundation record about pingzhuang basin, a lot of sino - foreign geothermal geology record and investigation of field geology, measuring of ground temperature in person and geo - chemical analysis of ascension spring, gushing water of fault, the fact that the anomaly of geothermal gradient of pingzhuang basin, which is in region of low geothermal gradient, is caused by redistribution of conduction - oriented geothermal heat flow which is result from upheaval and depression of basin foundation bed is pointed out. after the field of ground temperature is simulated under the background of conduction - oriented geothermal heat flow by means of ansys, the characteristic of ground temperature distribution of top surface of basin foundation bed ( yixian team ) is revealed. the sound condition of transmissibility fault and feeding water source, which are imperative in formation of the low - medium temperature geothermal system of convective type, is possessed in pingzhuang basin

Jiyang depression is a field where nonhydrocarbon is rich. these resources have close relation with the activities of the volcanos. at the same time, the activities of volcanos have deep contact with the activities of the faults. the growth of the faults in jiyang depression is great. by the research of the index number of the faults growth and the other researches, nw direction faults are the most ones in mesozoic, nw and ne and approximately ew directions all exist in cenozoic. the above reflects the whole geotectonic background that sinistral shearing stress field exists in mesozoic, but dextral shearing stress field exists in cenozoic

Some conclusions are listed as follows : the plateform cover cap of ordos basin and its circumference areas can be divided into five tectonic sequences. the tectonic evolution of ordos basin can be classified in six stages : the basement formation phase ( from archeozoic to paleoproterozoic ) ; the aulacogen phase ( from mesoproterozoic to neoproterozoic ) ; the north china continental sea phase ( from sinian to early - paleozoic ) ; the north china intracratonic depression phase ( from late - paleozoic to early mesozoic ) ; large ordos inland basin phase and the formation of independent ordos basin ( mid - late mesozoic ) ; fault basin phase around the ordos basin ( cenozoic )

The meso - cenozoic evolution of bachu fault - uplift is closely related to its south and north subsiding foredeep. under the background of indian plate subducting under asia - europe plate, bachu forebulge was greatly affected by the development of southwest depression and awati depression. almost all of its structure reversed, and as a result of it, both of its south and north boundary migrated. according to its evolution history and its feature, the authors tentatively use both - side migration model to interpret the evolution of compound forebulge. since triassic, almost all the spheres above lithosphere synchronously became flexure. because transpressional stress field became increasingly strong, bachu forebulge continued uplifting and big faults formed. then, bachu uplift, as a whole, slipped upward along those big faults and showed migrating toward thrust zone in plane. in tectonic tranquility, the lithosphere bounded back and in consequence of it, bachu uplift slipped down and showed migration toward craton, at that moment negative inversion structures developed. while the forebulge migrated toward its south and north foredeep, it was very possible that locally extensional stress appeared in the forebulge

With a differential accumulation analysis of the fault closeness and the difference of faulted reservoir in beitang depression, it is suggested that ( 1 ) an inactive fault in clastic sequence may mainly restrict hydrocarbon migration ; ( 2 ) undercompacted shales with overpressure can lead to strongly restricting hydrocarbon migration along faults ; ( 3 ) hydrocarbon segregation associated with fault traps more probably takes place in undercompacted zone with abnormal hydropressure
