“九·五”期间 ,我们对塔里木盆地库尔勒鼻凸—草湖凹陷油气勘探靶区进行了详细的研究。这个地区 ,经过十余年勘探 ,成果不理想。因此 ,有的研究者认为无进一步勘探的价值 ,有的专家则认为是有利的后备区。通过研究 ,我们认为 ,库尔勒鼻凸由于长期暴露 ,无进一步勘探价值 ;而草湖凹陷虽不是象阿克库勒凸起那样的优越的勘探区 ,但仍具备一定勘探前景 ,可以作为较为有利的后备接替勘探区。有利区块为小干湖区块和草 1井区块 ,其次是草湖凹陷西斜坡。  相似文献   

Tectonic Characteristics and Evolution of the Taiwan Strait     

Gao Tianjun Bureau of Geology  Mineral Resources of Fujian Province  Fuzhou  Fujianand Huang Hui Geoscience Institute of Fujian Province  Fuzhou  Fujian Jiang Minxi 《《地质学报》英文版》1995,69(1):1-13

The Taiwan Strait is a part of the continental-margin rift of eastern China, which can tectonically be divided into the Taiwan Strait basin, southwestern Taiwan basin and Penhu-Beigang uplift. The basins are structurally semi-graban down-faulted ones in character. The Cretaceous-Cenozoic sedimentary strata in the basins have a maximum thickness of over 10,000 m. The formation and development of the Taiwan Strait rift were not only affected by both the East China Sea basin and South China Sea basin but also closely related to the Central Range collision orogen of Taiwan. In the Cenozoic, the Taiwan Strait area experienced, under the influence of a multiple of tectonic mechanisms, three stages of evolution: poly-centre downfault-ing, down warping-faulting and foreland basin formation. The depositional centres of the basins migrated from west to east during the Tertiary, resulting in the thinning of the Palaeogene strata from west to east but that of the Neogene in the reverse direction. All this determine  相似文献   

Expert System for Statistical Prediction of Mineral Deposits on Middle and Large Scales     

Zhao Pengda Hu Guangdao Li XinzhongFaculty of Mineral Resources  China University of Geosciences  Wuhan 《中国地质大学学报(英文版)》1995,(2)

The expert system for statistical prediction of mineral deposits on middle and large scales takes the system of scientific exploration theories, criteria and methods proposed by Professor Zhao Pengda as the field expert knowledge. At present the developed system focuses on two aspects: synthetic exploration and quantitative exploration. Among the three basic theories for the prediction of deposits, it highlights the applications of seeking anomaly theory. This system is characteristic in the determination of geological background, the study of geological anomalies and the delineation of geological background, the study of geological anomalies and the delineation of mineralization anomalies. The system combines closely the knowledge base, method base and database ,integrates the input and output information of multi-sources and multi-variables, data , graphs and imagine processing system and inquiring system as a whole . So the system can meet in general all kinds of demands in statistical prediction of m  相似文献

福州地区地壳结构的地震转换波测深研究   总被引：2，自引：0，他引：2       下载免费PDF全文

邵学钟  顾忠华 《地震地质》1993,15(2):174-180

地震转换波测深法首次在我国东南沿海的福州地区进行地壳深部构造的探测,得出了该区地壳中的4个主要界面的构造形态图和沿北东方向穿越本区的地壳深部构造剖面图。查明闽江断裂由两条北西向产状较陡的超壳断裂组成,福州断陷盆地的深部上地壳G界面呈条带状下沉,下地壳C、C_1界面和M面及壳内低速层均相对上隆,这一结果为解释本区高地热异常提供了深部依据  相似文献   

A QUASI-TWO-DIMENSIONAL STREAM TUBE MODEL FOR SIMULATING FLOW IN ALLUVIAL RIVERS     

LI Yitian  XIE Jianheng Wuhan University of Hydraulic  Electric Engineering Wuhan University of Hydraulic  Electric Engineering 《国际泥沙研究》1993,(1)

I. INTRODUCTIONIt is necessary, sometimes, to predict river bed deformahon during the alanning and design stages of a hydraulic project. As the nuvial process is quite complicated, the I --Dmathematical models currently in use can not satisfy the various needs in hydraulic engineering. Particularly in engineering practice, there is a strong desire of knowing the hydraulicconditions and river bed deformation in details. Some two dimensional models as well asqusi--two--dissensional models …  相似文献   

ASSESSMENT OF THE EFFECTIVE RANK OF A (CO)VARIANCE MATRIX: A NON-PARAMETRIC GOODNESS-OF-FIT TEST

Each eigenvector of the dispersion matrix[X]~T[X]was shown to be a partial predictor of the originaldata matrix [X],the sum of the predictions from the individual principal components being equal to theexpectance of [X].By comparing the distributions of the members of two neighbouring predictedmatrices,[X]_(1...i)and [X](1...i+1)(i.e.the sums of the first i and i+1 individual predictions respectively),it was shown that they should be indistinguishable provided that i is equal to or greater than the effectiverank of [X],and significantly different otherwise.This was confirmed by analysing the visible absorptionspectra of methyl orange and methyl red solutions as well as the Raman spectra of Na_2SO_4 and MgSO_4solutions.On the grounds of these findings,a non-parametric goodness-of-fit test for assessing theeffective rank of[X]was proposed which proved to be comparatively conservative and more robust thanmost currently used tests.  相似文献
