INTRODUCTION Since the publication of Dr. J. G. Andersson's important "Essays onthe Cenozoic of Northern China" in 1923 much material has accumulated, partlyas the result of the explorations by the Geological Survey of China and partlythrough the expeditions sent out by other institutions, especial1y the Central 相似文献

20071073 Huang Tiedong(No.1 Geological Team of Xinjiang Bureau of Exploration and Mining,Changji,Xinjiang 831100,China) Formation of the Salt Lake and KNO_3 Ore in the Kumishi Block-Falling Basin in Xin- jiang(Hydrogeology & Engineering Geology, ISSN1000-3665,CN11-2202/P,32(6), 2005,p.20-24,4 illus.,3 tables,8 refs.) Key words:niter,salt deposits,Xinjiang The Kumishi Basin,a Cenozoic block- falling basin,has been controlled by a dry continental climate and continuously under- went a concentration process due to evapora- tion.The rock salt began to form in the late Pliocene to Pleistocene(35 ka B.P.).The thick rock salt bodies assembled in the late Holocene(4.5 ka B.P.)because of the stable crust and the continuous dry climate.With the evolution into the dry salt lake stage,the brines occurring in the crystals further con- centrated and the liquid-phase KNO_3 formed,which is overlain by K-rich rock salt. 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

针对冰川沉积系列细砂粉砂在埋藏前的曝光问题,笔者等人在帕米尔阿依直苏冰川做了观察.本文结合这些观察结果从沉积学角度讨论冰川沉积系列在产生、搬运、沉积过程中的曝光问题,并参考前人研究,将各类冰川沉积进行归纳.认为组成冰碛3个来源的细粒物质中,风成的全部曝光、岩壁风化碎屑部分曝光、冰川侵蚀岩屑不曝光;3个沉积系列中,冰水沉积完全曝光、冰川接触沉积中冰砾阜完全曝光、蛇形丘基本不曝光;冰碛物在沉积过程中,冰面融出碛基本上曝光、冰下滞碛和融出碛不曝光.本文根据分析,给出了冰川沉积系列曝光评估参考值. 相似文献

Felsic igneous rocks are of widespread magma types in continental orogenic belt, the petrologic genesis of which provides very important indication for understanding crustal evolution and melting geodynamic process within orogenic belt. Because of the differences of meltingdynamic condition, e.g. (1) composition of source rock; (2) physical chemistry conditions such as temperature, pressure etc.; (3) composition of residual phases and so on, felsic igneous rocks exhibit distinctly diverse petro… 相似文献
