In order to raise the level of reflection seismology data processing and to test the method of velocity estimation and migration imaging, the geophysical organizations, such as IFP (institute Francois de Petrole) and SEG/EAGE, have proposed 2D Marmousi model and 3D salt dome model, which have widely used in explorative geophysics. However, those two models are based on the geological background of Europe and the Middle Eastern, which reflects the sedimentary character of marine facies. In order to accelerate our terrestrial facies reservoir geophysics research, to meet the need of our country to method and technique and to make geological model for testing seismic data processing be able to demonstrate the special character of our terrestrial sedimentary facies, the academic committee of reservoir geophysics project, suggested to set up a typical model for china. For realizing this suggestion, Chen Shu Min, Guan Ye Jun, and Fu You Sheng from Daqing oil field proposed 2D geology model, so called china terrestrial facies fault depression model, based on the practice interpretation result given by Wang Pu Jun、 Shan Xian Long from Changchun Science and Technique University, as a testing tool for research of methodology in the reservoir project. Liu Hong and Gao Hong Wei from the institute of geology and geophysics, CAS, completed the tessellation of the proposed terrestrial facies fault depression model and digitalization of velocity model. After that, Dong Liang guo, Wang Hua Zhong from Tongji University carried out the seismic reflection wave numerical simulation by means of self developed simulation software, worked out a 60 fold seismic data on the model for reference in this research area. Terrestrial facies fault depression model show the structural characteristics of Daqing igneous (Fig.1). The length of whole model is 60km, depth 4km; the deep tectonics is very complex, the main characters of tectonics are as followes. 1. Under the action of rise igneous, fault

Magnetic activity indices are widely used in theoretical studies of solar-terrestrial coupling and space weather prediction. However, the indices suffer from various uncertainties, which limit their application and even mislead to incorrect conclu-sion. In this paper we analyze three most popular indices, Kp, AE and Dst. Three categories of uncertainties in magnetic indices are discussed: "data uncertainty" originating from inadequate data processing, "station uncertainty" caused by in-complete station covering, and "physical uncertainty" stemming from unclear physical mechanism. A comparison between magnetic disturbances and related indices indicate that the residual Sq will cause an uncertainty of 1―2 in K meas-urement, the uncertainty in saturated AE is as much as 50%, and the uncertainty in Dst index caused by the partial ring currents is about a half of the partial ring cur-rent.

提高地震资料分辨率的重要手段是采用反褶积技术。反褶积方法很多 ,如子波反褶积、脉冲反褶积和预测反褶积等。这些方法各有优缺点 ,在高分辨率资料处理中应用受到许多条件制约 ,不能有效地提高资料的分辨率 ,其效果不能满足解释人员的要求。作频率域地表一致性反褶积需要对记录进行频谱分析和频谱分解 ,同时要设计反褶积算子 ,然后在共炮点域和共接收点域分两步对资料进行褶积。这种方法能够展宽频谱 ,压缩地震子波 ,并能校正地震信号的相位谱 ,输出零相位子波 ,较大程度地提高地震资料的分辨率。该方法在胜利油田车2 2地区三维等资料处理中应用。

On the basis of oceanic geological and geophysical observations the global plate tectonics theory wasput forward in the late 1960s. It inherited the essence of mobilism of continental drift and sea-floorspreading, caused a revolution of earth sciences in the twentieth century. But plate tectonics cannotsatisfactorily explain the complicated geological phenomena of continents, it fails in elucidating

On the basis of field expeditions into different parts of the Badain Jaran Desert, new evidence of landscape evolution and precipitation changes during the last 30 000 years has been found from the geomorphological, sedimentological and geochronological studies of the megadune. Different cemented surfaces of palaeo-dunes have been observed in many localities, which are representatives of relatively moister environment. The chronological data show that four periods of more humid environment occurred in the past 30 000 years. The stabilization of dunes in a large scale and the existence of many palaeo-lakes and lacustrine terraces confirm the periodic fluctuations of climate. It implies that the intensity of westerlies and Eastasian monsoons varied in the region of Alashan, and the periods of higher precipitation took place even in the times close to the last glacial maximum.

Discovered in Early Proterozoic Xuanlong iron ore deposits are six genera of fossil iron bacteria, i. e. sphere (coenobium of) rod-shaped (monomer) Naumanniella, ellipsoid elliptical Ochrobium,sphere spherical Siderocapsa and chain spherical Siderococcus, chain rod-shaped Leptothrix and Lieskeella, and six genera of fossil blue bacteria, namely sphere spherical Gloeocapsa, Synechocystis and Globobacter, chain spherical Anabaena and Nostoc, and con-strictive septate tubular Nodularia. The biomineralized monomers and coenobia of the two cate-gories of bacteria, together with hematite plates made up the bacteria pelletal, bacteria silky, bacteria fibrous and clasty bacteria pelletal textural lamina. The bacteria pelletal laminae com-bined with other bacteria laminae to make up oncolite, stromatolite and laminate. The precipita-tion of iron oxide was accelerated due to iron and blue bacteria cohabiting on microbial film or mat. The Xuanlong iron ore deposits are microbial binding ore deposits of ocean source.
