Based on the ArcGIS geographic information system and the ORACLE database management system,this paper reports our studies on the technology of Marine Engineering Geological Exploration Information System(MEGEIS). By analyzing system structure,designing function modules and discussing data management,this paper systematically proposes a framework of technol-ogy to integrate,manage,and analyze the seabed information comprehensively. Then,the technology is applied to the design and development of the Bohai Sea Oilfield Paradigm Area Information System. The system can not only meet the practical demands of marine resources exploration and exploitation in the Bohai Sea oilfield,but also serve as a preparatory work in theory and technology for the realization of the 'Digital Seabed'.

By analyzing the magnetic anomalies,the linear magnetic anomalies in the middle Okinawa Trough are *** means that the crust along the spreading axis is broken,and new oceanic crust is *** data have revealed that a model of three extensive episodes occurs in the Okinawa Trough,which can be named as“doming episode” from the Middle to Late Miocene(Phase I),the episode from the Pliocence to Early Pleistocene(Phase Ⅱ),and the recent“spreading episode”(Phase Ⅲ).The magnetic anomalies in the middle Okinawa Trough are very similar to those found in the middle Red Sea,indicating that the Okinawa Trough is developing towards the “Red Sea stage”.Similar to the Red Sea,there are a “main trough”and a “axial trough”in the Okinawa Trough.

This paper discusses the designing plan of ORACLE-based Bohai Sea engineering geology database structure from requisition analysis, conceptual structure analysis, logical structure analysis, physical structure analysis and security designing. In the study, we used the object-oriented Unified Modeling Language (UML) to model the conceptual structure of the database and used the powerful function of data management which the object-oriented and relational database ORACLE provides to organize and manage the storage space and improve its security performance. By this means, the database can provide rapid and highly effective performance in data storage, maintenance and query to satisfy the application requisition of the Bohai Sea Oilfield Paradigm Area Information System.

The research of the geophysical survey in the cast of the southern Yellow Sea (SYS) (122°-125°E) in 1999 reveals that the SYS has a structure of three-uplifts and two-basins. The structure can be well concordant with the gravity and magnetic anomalies. In the basins, most of the gravity and magnetic anomalies are low and gentle. As well in the uplifts, the gravity anomalies are high positive ones,but the magnetic anomalies are plus and minus variant *** data show that the mid-uplift is a Cenozoic one. The Paleozoic is under the Q+N strata, the thickness of which is less than 1 km, with no Palaeogene. The Wunansha uplift area and the Sunan uplift area have good continuity, which indicates that they belong to the same geological unit. The basin in the northern part of SYS, which developed in the late Cretaceous period, is a Cenozoic one mainly made up of Cenozoic sediment. On the contrary, the basin in the southern part is the seaward extension of Subei basin and is a medial Cenozoic sediment basin mainly made up of Cenozoic sediment. Because of the striking left-lateral sense translation of Tanlu fault zone, the east plate of fault zone moved northward on a large scale, which generated a massive north-south pull-apart stress field to make the earth crust pulled apart, revolved and tilted, and the pulling-apart basin came into being in the upper part of the crust.

采用中国科学院海洋研究所“科学1号”调查船及国家海洋局“向阳红9号”调查船最近几年在冲绳海槽宫古段进行海底地形及反射地震调查所取得的数据,首次详细展示了冲绳海槽宫古段南北长约200km区域内中央地堑的形态及空间展布特征。本文给出的成果大大加深了关于冲绳海槽中央地堑各种变化的认识。指出,按照形态,中央地堑分为U型、V型和半地堑三种。其中大部分中央地堑为U型地堑。地堑的深度40～250m,宽度6～14km,长度17～33km。冲绳海槽宫古段的最大水深为2244.4m,位于中央地堑城阳段北端底部靠东的一侧(125°19.3′E,25°49.8′N)。本研究区的中央地堑可分为断续的9段,从东北向西南大致呈右旋雁行排列。但黄岛段相对于崂山段,城阳段相对于莱西段,李仓段相对于城阳段又稍微向西偏出,呈现为左旋雁行排列。地堑的走向一般为N60°E左右,相对于冲绳海槽的走向更偏向于东西方向,偏角在15°左右。各段中央地堑是被NW向断裂错开的。这些断裂在海底表现为明显的海底断崖地貌和陡沟地貌,在地震剖面上表现为明显的地层错位,其错位的幅度往往老地层比新地层要大。根据地震剖面分析,这些NW向的断裂应该是走滑性质的。本文展示的中央地堑在形态上和空间展布形式上都和扩张洋脊类似。莱西段和城阳段中央地堑之间重叠地堑,在形式上也类似于扩张洋脊的重叠扩张中心。从地堑深度较浅并发育重叠地堑来分析,冲绳海槽的扩张速率应当介于慢速扩张和中速扩张之间。本研究区莱西段、即墨段和平度段海底地形相对较高,中央地堑深度变浅,并发育重叠中央地堑,应该相当于快速扩张大洋中脊的轴高,可能是正在孕育岩浆活动的位置。目前我们所观测到的中央地堑的错断和有规律的排列说明海槽的主体演化过程已经在拉张盆地和断陷盆地的基础上上升到一个更高的阶段。本文根据中央地堑的展布形式、重叠中央地堑,及其两侧中央地堑中的海底山推测此区域海底扩张可能正在进行。

Based on compositive analysis and interpretation of the observed and historical data, the geophysical field characters and structural properties of the Gagua “Wedge” Zone of the sea area east of Taiwan Island and the primary tectonic stress direction and its variabilities of backarc spreading in the southern Okinawa Trough are studied. It is concluded from the study results that the Gagua “Wedge” Zone is structurally consistent with the Gagua ridge and two fault basins on both sides of the Gagua ridge, and adjusts the moving direction and distance of the western Philippine Sea plate to make the northwestward motion of the plate on its east side change to the northward subduction of the plate on its west side so that the primary tectonic stress direction of the Okinawa Trough changed from NW-SE to nearly N-S, which provided the stress source for the Okinawa Trough to enter the second spreading stage.

In this paper, the upper structural layer of thesouthern Yellow Sea Basin (SYSB) is further divided intothree layers based on the latest obtained high-resolution sin-gle-channel seismic profiles. Combined with the boreholedata, the characteristics and evolvement of structure andenvironment since middle-late Tertiary are discussed. Thestudy shows that the acoustic-base indicated by shallowseismic profiles represents the basic shape of the SYSB inlate Oligocene-early Miocene. Based on the comprehensiveanalysis of some typical profiles crossing the basin aboutseismostratigraphy, gravity and magnetics, the basin edgefault and some basin inner structure are identified. Fur-thermore, the acoustic-base is classified into four types ofbasal lithofacies: Eogene basin basement, Paleozoic base-ment, Mesozoic basement and magma intrusion basement.
