On the basis of the above sedimentary research, combining the identification of well logging and seismic facies. The detailed research on the character and space-time evolvement of the lithofacies-paleogeography of Silurian-Devonian has been carvied out, and the research indicates that in the process of sedimentary evolvement, the character of lithofacies paleogeography is different in each phase, but it is succession.

在上述沉积相研究基础上，结合测井相、地震相的识别，对塔里木盆地志留－泥盆系岩相古地理特征及时空演化进行了详细研究，研究表明在志留－泥盆纪沉积演化过程中，岩相古地理分布特征在各个时期存在差异性，但在整个古地理演化过程中，又具有继承性。

Sedimentary testate amoebae are very useful in quantitative reconstruction of sea level changes, paleohydrology, and paleoclimate, which are mainly in the studies of paleolimnology and human activities.

In spite of its short history, it develops rapidly and is widely used in core correlation, material source identification, sediment tracing, ecosystem evolution, paleocliamtic and paleoenvironmental study, pedology, environmental pollution, oil and gas exploration and paleomagnetism.

尽管其历史不长，它的发展却异常迅速，在样芯对比、物质来源鉴别、泥沙运移示踪、流域生态环境演替、古气候和古环境研究、土壤发生学、环境污染、油气勘探、古地磁学等领域得到了广泛应用。

Now, let us introduce some peculiar animals for you, you can choose among of them and come up with your own plasticine print making after doing some line sketching to make it more vigorous and old-age's perception.

其实，我们中华文化里也有许多传说中的古兽，现在为你们介绍其中几种奇特的古兽，你可以选择一种你喜欢的并加以线描练习，然后制作版画，让你所制作的古兽，看起来感觉更"古老"，更"神气"！

The fault trends towards northwest, in which the hanging wall consists of Archean-Proterozoic metamorphic strata and Paleozoic plutonic intrusive body, and the footwall consists of Jurassic sediments, thrusting from northwest to southeast.

断层倾向北西，上盘由太古宙-元古宙变质地层和古生代深成侵入体构成，下盘为侏罗纪沉积，由北西向南东方向逆冲。

The result of factor analysis can provide the changes of relative precipitation and temperature variations. In trace elements, Cu, As, Zn, Pb and Ni were apparently enrichmented in soil layers and are sensitive to climatic changes. Carbon isotope is more sensitive to climatic changes than that of oxygen isotope in loess stratigraphy. The heavy mineral are varified in the loess stratigraphy, but their content differences between loess and palaeosol is little. Though the palynologic analyses results reveal that pollens and spores are fewer in the loess stratigraphy, they differ greatly in loess layer and palaeosol layer not only in species but also in types, i. e., the pollens and spores indicating warm and moist climate, such as Lles, Podocarpus, Polopydium, Pteris grerilliana Wall, Pterocarya and Juglans appear in palaeosol layers, while those indicating cold and dry climate such as Ephedra, Artemisia, Chinopodiaceae, Picea and Abies exist mainly in loess layers. The pollen content of broad-leaved tree mainly consisting of Pterocarya is up to 60% in palaeosol 〓, while the content of Ephedra is more than 50% in 〓 loess layer, showing that the environment differed greatly when 〓 and 〓 were formed.

当然，常量元素氧化物的组合因子分析结果可提供相对降水与相对温度在剖面的变化，因而来反映气候状况更为理想；微量元素中Cu、As、Zn、Pb与Ni在成土过程中富集明显，亦较好地反映了气候变化；稳定同位素中的碳同位素比氧同位素更能敏感记录气候的变化；研究区黄土地层中重矿物种类较多，但黄土层与古土壤层中含量差异不大；孢粉分析结果揭示，尽管研究区黄土层中孢粉总量相对较为贫乏，但黄土层与古土壤层中孢粉种属相差较大：在古土壤层内出现了指示相对暖湿环境的冬青属、罗汉松属、水龙骨属、林下凤尾蕨、枫杨、胡桃等植物孢粉，而黄土层中麻黄、藜科、蒿属及冷杉、云杉含量较高。

This paper briefly introduces the basic fact of the existence of the PaleoTethys Ocean in the Lungmu Co-Shuanghu suture, i.e. the ages and natures of Early Paleozoic ophiolites, Permian ophiolites, Devonian-Permian radiolarian cherts, accretionary slabs of different natures, two types of tectonic mrlange zones and covers of ophiolites. The starting time of the Paleo-Tethys Ocean in Qiangtang may be traced back to Early Paleozoic and the records about the oceanic basin evolution persisted from the Late Devonian to Late Triassic.
