The Tan-Lu fault zone joins the Dabie Mountains on its eastern margin, and offsets the Dabie and Sulu orogenic belts sinistrally for about 500 kin. On the basis of calculation of temperature and pressure experienced by the two phases of the fault zone as well as the thermo-chronological information on mylonite from the earlier and later Tan-Lu fault zones on the eastern margin of the Dabie Mountains, this paper discusses the delamination history and uplifting magnitudes of the Dabie Mountains from earlier Jurassic to earlier Cretaceous. From mineral assemblages, mineral deformation and muscovite-chlorite geothermometry calculation, it is known that the temperature experienced by the two phases of Tan-Lu fault zones are between 40℃ and 450℃, and the confining pressures are between 0.25Gpa and 0.36GPa for the earlier shear zones and 0.24-0.39GPa for the late shear zones. According to the geobarometry of Si-in-phengite and by considering shear heating and tectonic over-pressure, it is concluded that the maximum formation depths for the two phases of the ductile shear zones are not more than 12 kin. Differential formation depths for the two phases of shear zones are 1-2 km at most. At about 190 Ma and 128 Ma, the Tan-Lu fault zone experienced two phases of cooling events. During this period, the eastem margin of the Dabie Mountains experienced a tectonic calm period and no uplifting. According to information from the Tan-Lu fault zone, the uplifting magnitudes of the Dabie orogenic belts are not more than 12 km during the earlier Cretaceous. 相似文献

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.

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

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

Sedimentary mineral deposits were not formed simply as product of simplereactions through a single kind of factors,but were outputs of intricate reactionsamong a complex set of evolutionary natural environmental agents.They were formedat least through three different stages,viz.,the imbibition and concentration ofore forming materials;the geochemical enrichment;and the physical concentrationstages(Fig.1).As to industrial phosphorites,physical enrichmnt is of paramountimportance.It seems,almost all of the world industrial phosphorite deposits wereformed as such.Our idea of physical enrichment was first set up in 1980,during the 2ndNational Symposium on Mineral Deposits at Hongchow.Since then,lots of newevidences had been added up.In this paper,only those of phosphorite deposits are described. 相似文献

1) The newly found specimens confirm the fact that Sinanthropusrepresents an independent hominid type distinctly inferior to Neanderthal manand showing definite anthropoid peculiarities in many features. 2) The teeth of Sinanthropus exceed in size those of recent andNeanderthal man.Premolars and molars are very complicated in their pattern,especially in regard to the abundance of wrinkles and they are hardly inferiorto those of chimpanzee,but they exceed them in coarseness. The upper canine of Sinanthropus is long and wide and projects re-markably like a tusk beyond the level of P.The upper milk canine is isolated from both its neighbors by gaps,in the dentition of milk teeth.The teeth ofrecent man,in crowns as well as in roots,are simplified and reduced in com-parison to those of Sinanthropus;this primitiveness is not basic but a secondaryacquisition. 3) The teeth(milk and permanent)of Sinanthropus are more variablein size than those of a corresponding population of recent man.Therefore,a sexual difference must be recognized like that of the Simiidae. 4) In two(three)of the four adult jaws there are hyperostoses—"Torus mandibularis"—on the inner side of the alveolar part,the largest ofwhich is situated just linguad of the alveolar septum between P_1 and P_2.Thesame peculiarity may be found in prehistoric and in recent Chinese jaws and,according to Fürst,is very characteristic of the Mongolian racial group ofmankind,especially the Eskimo. 5) In Sinanthropus all upper incisors are very much.shovel-shaped.This peculiarity too is found in the corresponding teeth of the recent Mongolianrace in sometimes nearly 100％ of the population. 6) The facts mentioned under 4) and 5) seem to prove that Sinan-thropus takes his place in the direct line leading to recent man and that amongpresent-day mankind the Mongolian group has the closest relation to Pekingman. 7) An inventory,of all specimens of Locality 1 leads to the con-clusion that the population of Choukoutien must have been composed of atleast 10 children,2 adolescents and 12 adults;perhaps one half of these weremale and the other half female. 8) Most of these individuals are represented by teeth or jaws only,some by skull fragments and two or three by specimens of body bones.Themissing bones cannot have been lost during the filling up of the cave or thefossilization process or during the subsequent excavations,but must have beenabsent already when the bones were imbedded in the rocks. 9) The Sinanthropus remains must have been brought into the caveas parts already severed from the body;perhaps they represent trophies or,more probably,the hunting spoil of head hunters. 10) There is not the least indication that this hunter was another andmore advanced hominid type than Sinanthropus himself.Sinanthropus wasthe bearer of the cave culture of Choukoutien,the fire-maker and the manu-facture of the implements,perhaps also both the hunter and the cannibalwho preyed on people of his own kind. 相似文献

The characteristics of the Triassic sequences developed in the Lower Yangtze area display some great changes in both environment and climate. The change of environment was a transition from marine to continent via alternating environments. The change of climate was a transition from tropic （torrid） to warm and wet climate via subtropic dry climate. The type variations of the sequences were from the marine sequences to the continental sequences, corresponding to the changes of environments and climates. Sequence 1 is a type II of sequence of mixed elastic and carbonate sediments; sequence 2 is a type I of sequence of carbonate platform; sequence 3 is a type I of sequence of carbonate tidal flat-salt lagoon, sequence 4 is a type iI of sequence of lacustrine within marine layers, and sequence 5 is a sequence of lacustrine-swamp. The development, distribution and preservation of those sequences reveal the tectonic controls and their changes in the background. The collision between the Yangtze plate and the North China plate was a great geological event in the geological history, but the timing of the collision is still disputed. However, the characteristics of Triassic sequence stratigraphy and sea level changes in the Lower Yangtze area responded to this collision. The collision started at the beginning of middle Triassic and the great regression in the Lower Yangtze area started 22Ma earlier than those in the world. The tectonic conditions occurred before and during the collision controlled the development of sequences and type changes. 相似文献
