THE STUDY ON GEOPHYSICAL DATA ACQUISITION AND PROCESSING OF THE KOREA CONTINENTAL SHELF.
A 2-D marine seismic survey has been carried out to depict the sedimentary basin structures in the eastern part of the Kunsan Basin in the Yellow sea in 2002. This seismic data acquisition and processing project is funded by the program of the national geological map compilation and resources investigation of the Ministry of Commerce, Industry and Energy.
The project aims at (1) providing basic marine geological and geophysical informations to the government for planning of the national energy and mineral resources supply program and intergovernmental negotiation of the EEZ boundary and (2) estimating of the energy resources potential of the offshore area.
The marine geophysical data acquisition, processing and interpretation program is planned to cover the whole sedimentary basin developed in the Korea continental shelf until 2009. In first phase of the project (2001-2004), the two dimensional marine seismic survey using R/V Tamhae Ⅱ will be conducted in the Yellow Sea and the marine geological structure map of the Yellow Sea sedimentary basin will be published in 2004, the final yew of the first phase of the program.
RESULTS Of THE STUDY
The results of the seismic data acquisition and processing in 2002 are asfollow :
- Acreage of the survey : 15,000km2
- Number of survey lines : 11 seismic lines
- Total length of the lines 1,104 CMP Line-km
Seismic stratigraphy interpretation was carried out in the northern part of the Kunsan Basin using the seismic profiles acquired in 2001 by R/V Tamhae Ⅱ.
Four regional unconformities were identified in the northern part of Kunsan basin.The megasequence boundaries (MSB) and the megasequences (MS) are referred to as MSB 1 to MSB 4 and MS 1 to MS 4, respectively, from oldest to youngest. Each MS rests on its corresponding MSB. It is suggested the study area was formed as a pull-apart basin with a WNW-ESE striking right-lateral shearing stress, showing structural elements developed parallel or subparallel to the idealized strain ellipsoid.Major rifting occurred in periods between MSB 1 and MSB 2, and terminated before MSB 3, then the area experienced inversion after MSB 4.
MS 1 consists of 4 step development in ascending order, i.e. (1) deposition of much volcanic flow or volcanoclactics during major rifting, (2) fluvial deposition with complex incised valleys, (3) lacustrine deposition in depocenter of the basin and in deep sags along the major faults, (4) transition to fluvial deposition by the uplift of the crustal blocks. MS 25l3 are restrictedly deposited.
APPLICATION OF THE STUDY RESULTS
Science and Technology Research
o Research of formation and evolution of the sedimentary basins in the Korea continental shelf
o To provide basic data and informations such as geological structure and stratigraphy to assess marine mineral and energy resources.
o To provide basic data for tectonic researches of the Korea peninsula and the Northeast Asia.
Socioeconomic Application
o To provide data and informations to plan national energy supply program.
- Estimation of the potential value of the energy resources reserved in the Korea continental shelf
o Data acquisition for the determination of the EEZ boundary and secure the offshore sovereignty and marine resources.
o To support technical cooperation with North Korea for the offshore mineral and energy resources development program.
Public and Industrial Application
o Domestic and foreign offshore hydrocarbon exploration and deep sea geophysical exploration.
o To provide basic data and exploration technology for the public purpose civil engineering and construction project.
o Training technical manpower for marine exploration.
