These geomorphic units of paleogeography constitute the basic model of paleocontinent , littoral - neritic sea and carbonate plateform at that stage , and this depositional model is similar to the pattern of the east china continent and ocean , which is the result of evolution during the past long geologic age 这些古地理地貌单元构成了湖北省泥盆纪时期古陆滨浅海和碳酸盐岩台地的基本沉积模式，这种沉积模式与现今中国东海大陆、海洋格局基本一致，亦是经过了漫长地质历史时期演化，而形成现今这种格局的。

In this paper , the authors prove the sedimentary environment of every lithostratigraphic unit of devonian , and precisely divide the geomorphic units of petrologic paleogeography of that period , based on the multiple division and detailed study to the petrostratigraphy , biostrtigraphy and sequence stratigraphy of devonian in hubei and its adjacent provinces 摘要通过对湖北及邻省泥盆纪岩石地层、生物地层与层序地层进行多重划分对比和详细研究，以大量实际资料确定该时期各岩石地层单位的沉积环境，准确划分出该时期岩相古地理地貌单元。

Phosphate deposits are distributed along the margin , platform and basin in the west yangtze area . the analysis methods include the paleogeography , petrology , organic geochemistry , geochemistry . the conclusions are drawn that the source of phosphate deposits distributed along the margin originate from the weathering production of continent , while phosphate deposits along the platform and basin gain phosphorus through hot spring on the buttom of the sea floor , which is brought to the sedimentary environment by rising sea - fluid , then accumulated by the organism and microorganism , meanwhile , basin phosphorite keep relatively higher organic carbon content 认为早寒武世早期古陆遭受风化，被剥蚀下来的产物成为潮坪型磷块岩的主要磷质来源，在碳酸盐岩台地发生的热点活动和上升洋流从盆底深部带来的磷质，共同作为台地型磷块岩的磷源，盆地型磷块岩的磷质同样是由热点活动和上升流携带至缺氧的沉积环境中，通过藻类或微生物的富集作用成岩，并保留了较高的有机碳含量。

By now international exploration for subtle trap is mainly used with paleogeography , which integrates geology , geophysics , geochemistry and drilling , among them , seismic method is getting more and more important . there are a couple of favorable conditions to form subtle trap reservoirs , which are dustpan structure , coexisted slope and sag framework , etc . they lead to form multiple and extensive non - structural traps 目前，国内外勘探隐蔽油气藏的方法主要是岩相古地理和古地貌分析法，常用的手段是地质、地球物理、地球化学和钻井方法的综合，其中地震方法在隐蔽油气藏勘探中起到了越来越重要的作用。
