There exists the juxtaposition of different tectonics corresponding to the differences in geochemical composition of granulite terranes, which results from the extrusion uplift.
According to the development of mylonitization between gneissic granite and its country rocks, it is considered that a large scale tectonic juxtaposition of ultrahigh-pressure rocks and the Yangtze continental crust mainly composed of granitoids occurred at high crustal level during exhumation.
Controlled by the asymmetrical wedge-shaped depression and the structural setup of its juxtaposition of uplifted and depressional units, as to the distribution of sedimentary facies zones of the S4 member, the western flank was asymmetrical with the eastern, and the northern part was different from the southern.
On the western gentle slope there were several tilting fault blocks controlled by the reverse normal faults, characterized by the juxtaposition of uplifted and depressional units.
The juxtaposition of east-and westdipping beds cropping out along opposite sides of the detachment results in a pseudo-anticline hundreds of km in length, known as the Front Fold or Triangle Zone.
The Precenozoic evolution of the geotectonics in the region has undergone a very complex history of terrane drifting, collision juxtaposition and jump of subduction zone
A procedure of numerical simulation for coherent phenomena in multiply scattering media is developed on the basis of the juxtaposition of a Monte Carlo stochastic method with an iterative approach to the solution of the Bethe-Salpeter equation.
The data on vibrational frequencies are interpreted on the basis of their juxtaposition with those from the fluorescence line narrowing spectrum of octaethylporphin and resonance Raman spectra of its complexes with copper and nickel.
By the examples of the Siberian Platform and Canadian Shield, it is shown that spatial juxtaposition of Phanerozoic diamond-bearing kimberlite fields with giant swarms of Precambrian mafic dikes is caused by both systematic and incidental events.
The third, Late Paleozoic period was marked by reworking of the continental crust with juxtaposition of all older crustal protoliths.
The mere juxtaposition of professionals will not result in actual interdisciplinary contributions.
Lithologic traps in granular limestones appear to be the principal type of subtle traps in the Western Liaohe Basin. Controlled by the asymmetrical wedge-shaped depression and the structural setup of its juxtaposition of uplifted and depressional units, as to the distribution of sedimentary facies zones of the S4 member, the western flank was asymmetrical with the eastern, and the northern part was different from the southern. The northern part of the western gentle slope was favourable for the formation...
Lithologic traps in granular limestones appear to be the principal type of subtle traps in the Western Liaohe Basin. Controlled by the asymmetrical wedge-shaped depression and the structural setup of its juxtaposition of uplifted and depressional units, as to the distribution of sedimentary facies zones of the S4 member, the western flank was asymmetrical with the eastern, and the northern part was different from the southern. The northern part of the western gentle slope was favourable for the formation of the granular limestones. The lithologic granular limestone oil pool in Gaosheng oil field was formed with the covering up granular limestones deposited on the gentle slope of the S4 member by the mudstone source rook of the S3 member.The pores of the granular limestone reservoir may be classified into two types, primary and secondary pores, i.e. primary-intergranular pores, secon dary-intergranular solution pores and fractures. The effective porosity of the reservoir mainly depends on the development of primary intergranu larpores, i.e. the pore space between oolitic and bioclastic grains.
The Western Liaohe wedge-shaped depression was formed as a result of uninterrupted pull-apart and down-slip of basement blocks along the normal fault under tensile stress, accompanied by continual expansion of the extent of paleogene sedimentary depression. There was a process of tilting of the basement blocks which slipped down along the arcuate fault planes. On the western gentle slope there were several tilting fault blocks controlled by the reverse normal faults, characterized by the juxtaposition...
The Western Liaohe wedge-shaped depression was formed as a result of uninterrupted pull-apart and down-slip of basement blocks along the normal fault under tensile stress, accompanied by continual expansion of the extent of paleogene sedimentary depression. There was a process of tilting of the basement blocks which slipped down along the arcuate fault planes. On the western gentle slope there were several tilting fault blocks controlled by the reverse normal faults, characterized by the juxtaposition of uplifted and depressional units. The source rocks of the S3 member overlapped the tilting fault blocks .Covered with deltaic and lake-bay carbonate deposits of the S4 member on the gentle slope, the subtle traps formed there were of varied types. the overlying traps controlled by fault blocks and the thick oil-sealed strati-graphic traps etc.According to the structural morphology of the basement, a tilting fault block can be divided into three parts, the fault plane, the fault subsidence and the fault slope .Controlled by the structure of fault blocks, overlying oil traps were formed within the corresponding structures of the overlying sedimentary rocks.The thick oil-sealed stratigraphic oil pools were formed as a result of updip denudation of the deltaic sandstones of the S4 member which permitted the escape of crudes to the surface where, after oxidation, the thick oil formed a seal below the unconformity surface.
The Yanshan movement occurred at the end of Cretaeens swept across the whole China. This movement gave rise to full-growth of the Qilianshan-Luliangshan-Helanshan ∈ structure,Since Himalayan movement, the new structural systems of upheaval belt or depression belt came to pass in juxtaposition or in transposition on the older strueturai systems, moreover Indosinian movement in turn led to both the west-wing fold belt and the reflexarc fold belt of the ∈ front arc uncomformably overlay on the folds produced...
The Yanshan movement occurred at the end of Cretaeens swept across the whole China. This movement gave rise to full-growth of the Qilianshan-Luliangshan-Helanshan ∈ structure,Since Himalayan movement, the new structural systems of upheaval belt or depression belt came to pass in juxtaposition or in transposition on the older strueturai systems, moreover Indosinian movement in turn led to both the west-wing fold belt and the reflexarc fold belt of the ∈ front arc uncomformably overlay on the folds produced by the Qilianshan movement. By means of drawing up both map of structural system of Yanshan stage and six lithofacies paleogeographic maps of Late Paleozoic age, the history of both the deformation and the formation from Qilianshan stage to Yanshan stage in this area can be traced, and combined with model experiment, the evolutionary changes of the structural systems from Devonian to Cretaceous in the Qilianshan region are then discussed.
