An exhumation model of the south Peloponnesus, Greece 总被引:1,自引:0,他引:1

An exhumation model comprising forward and backward thrusting and late orogenic collapse is proposed in order to explain
the kinematics of the tectonic windows in the south Peloponnesus. The model is based on mapping, mesoscopic structural data
and strain analysis. Syn-compressional thickening took place throughout the Oligocene and Early Miocene which includes the
subduction of the Pindos Ocean at the western margin of the Pelagonian microcontinent and the intracontinental subduction
of the Phyllite–Quartzite and the Plattenkalk series. The latter subduction was associated with blueschist metamorphism, westward-directed
ductile thrusting, and folding. The exhumation history of the deeper parts of the orogen began at the Oligocene–Miocene boundary
with the progressive entrance of the low-density crust and the Plattenkalk carbonates in the subduction zone. Increased buoyancy
caused: (a) the initiation of the Phyllite–Quartzite series extrusion; (b) vertical coaxial stretching; and (c) the evolution
of two pop-up structures, i.e. the Parnon and Taygetos anticlines. This syn-compressional exhumation was taking place in the
lower Miocene with decreasing rates from 7 to 1.5 mm/year. The change in the local stress field from compression to extension
began in the middle Miocene with the formation of hinterland-dipping normal faults. The exhumation/denudation rate caused
by the footwall uplift along these faults does not exceed 0.2 mm/year.

负压地层形成机制及其对油气藏的影响 总被引:10,自引:1,他引:10
具异常压力场特征的盆地在我国比较普遍,但更多的是研究超压体系,对于异常低压体系的成因与机制在国内还没有很好的解释。盆地内的广泛沉积造成的巨厚沉积地层,并在随后的地层抬升过程中造成的严重剥蚀,导致剥蚀反弹现象,从而形成负压区。由于地层的温度或其他因素的影响,也会造成局部的负压现象。根据百色盆地的负压现象,从其成因着手,分析其形成过程有其对该地区油气藏的影响。负压造成流体的局部回流,形成低压封隔窗,促使油气二次运移,从而改造油气藏的分布,形成一些与负压有关的油气藏。 相似文献

Geostatistical analysis of spatial random functions frequently uses sample variograms computed from increments of samples of a regionalized random variable. This paper addresses the theory of computing variograms not from increments but from spatial variances. The objective is to extract information about the point support space from the average or larger support data. The variance is understood as a parametric and second moment average feature of a population. However, it is well known that when the population is for a stationary random function, spatial variance within a region is a function of the size and geometry of the region and not a function of location. Spatial variance is conceptualized as an estimation variance between two physical regions or a region and itself. If such a spatial variance could be measured within several sizes of windows, such variances allow the computation of the sample variogram. The approach is extended to covariances between attributes that lead to the cross-variogram. The case of nonpoint sample support of the blocks or elements composing each window is also included. A numerical example illustrates the application of this conceptualization. 相似文献

相干能量梯度体现了相干数据的振幅变化,它比较有利于突出一些细小的地质特征变化,其属性比例融合是将两个数据体按照一定比例融合在一起生成新的数据体,而新数据体能更好的反映地质特征。实例表明,与相干属性相比,相干能量梯度属性对一些细小构造更敏感,而且可以根据不同方向、时间的切片对不同走向的断层进行追踪;与常规地震时间剖面相比,属性比例融合后的属性剖面,可以在剖面中显示两种属性体的断裂构造特性,减少单一属性体的不确定性。 相似文献

Early Cenozoic Mega Thrusting in the Qiangtang Block of the Northern Tibetan Plateau 总被引:2,自引:0,他引:2
WU Zhenhan YE Peisheng Patrick J. BAROSH HU Daogong LU Lu ZHANG Yaoling 《《地质学报》英文版》2012,86(4):799-809
Recent mapping and seismic survey reveal that intensive compression during the Early Cenozoic in the Qiangtang block of the central Tibetan Plateau formed an extensive complex of thrust sheets that moved relatively southward along several generally north-dipping great thrust systems. Those at the borders of the ~450 km wide block show it overrides the Lhasa block to the south and is overridden by the Hohxil-Bayanhar block to the north. The systems are mostly thin-skinned imbricate thrusts with associated folding. The thrust sheets are chiefly floored by Jurassic limestone that apparently slid over Triassic sandstone and shale, which is locally included, and ramped upward and over Paleocene-Eocene red-beds. Some central thrusts scooped deeper and carried up Paleozoic metamorphic rock, Permian carbonate and granite to form a central uplift that divides the Qiangtang block into two parts. These systems and their associated structures are unconformably overlain by little deformed Late Eocene-Oligocene volcanic rock or capped by Miocene lake beds. A thrust system in the northern part of the block, as well as one in the northern part of the adjacent Lhasa block, dip to the south and appear to be due to secondary adjustments within the thrust sheets. The relative southward displacement across this Early Cenozoic mega thrust system is in excess of 150 km in the Qiangtang block, and the average southward slip-rate of the southern Qiangtang thrusts ranged from 5.6 mm to 7.4 mm/a during the Late Eocene-Oligocene. This Early Cenozoic thrusting ended before the Early Miocene and was followed by Late Cenozoic crustal extension and strike-slip faulting within the Qiangtang block. The revelation and understanding of these thrust systems are very important for the evaluation of the petroleum resources of the region. 相似文献
