A FALCON® AGG and magnetic survey in the Glyde Sub-basin aims to define the structural pattern to identify unconventional hydrocarbon plays. The survey area consists of variable thick fluvial and lacustrine to shallow marginal marine carbonate-siliciclastic sequences and lesser volcanic rocks. The dominant tectonic feature identified on the AGG data is the Emu Fault Zone: a major structure of. 1 Basin Analysis Basin Analysis Introduction Mechanisms of Basin Formation Basin Classification Basins and Sequence Stratigraphy Summary Introduction Basin analysis - Study of sedimentary rocks to determine: Subsidence history Stratigraphic architecture Paleogeographic evolution Tools: Geology (outcrops, wireline logs, core) Geophysics (seismic, gravity, aeromag).
The structure exerts considerable influence on sediment accumulation in the basin. Seismic data from the adjacent continental shelf and gravity data from the basin suggest that the Romanche fracture extends into the West African continent as the Fenyi-Yakoe fault. The Keta basin is a graben that is modified by basement by: Sediments accumulate in a wide variety of environments, both on the continents and in the oceans. Some of the more important of these environments are illustrated in Figure Table provides a summary of the processes and sediment types that pertain to the various depositional environments illustrated in Figure Author: Steven Earle.

Attribute Name Values; Creator: Barday, Robert James; Abstract: In order to quantitatively examine the crustal structure of the Panama Basin without the benefit of local seismic refraction data, the following assumptions were made: (1) No significant lateral changes in density take place below a depth of 50 km.
(2) The densities of the crustal layers are those of a km standard section Cited by: 8. STRUCTURE OF THE PANAMA BASIN FROM MARINE GRAVITY DATA INTRODUCTION The Panama Basin is the region of the Eastern Equatorial Pacific that is bounded on the north and east by Central and America and on the south and west by the Carnegie and Cocos ridges.
It is an extremely complex region, encompassing portions of the Cocos. Free‐air and variable‐density Bouguer anomaly maps, a horizontal first derivative map of the Bouguer anomaly, and gravity models of profiles across and along the basin were used with existing geological and geophysical information to infer the structure of the basin.
The basin is Cited by: The Panama Basin is an area enclosed by the continental margins of Ecuador, Colombia and Panama to the East and North, and the Carnegie and Cocos ridges to the south and northwest. It sits within the Galapagos gore, a region of oceanic crust formed at the Cocos-Nazca spreading center, east of the East Pacific Rise (Hardy, ).Cited by: 2.
The structure and the tectonic development of the southern Panama plate boundary have been derived from an interpretation of marine geophysical data, including GLORIA (Geological LOng Range Inclined Asdic) long-range side-scan sonar and seismic reflection profiles, most of which were acquired in from a cruise of the RRS Charles Darwin.
Basin, by applying numerical inversion of the gravity data. The Global Gravity Data and the Sea Floor Topogra-phy databases (Sandwell and Smith, ) were employed in combination with the gravity data collected from the ship transects carried out during the SCAN 97 cruise.
Thickness of the depositional sequences obtained. Lake Albert’s basin geometry is a relatively simple full-graben structure, with a paired boundary fault and rider block feature on the southeastern margin of the basin and a single dominant normal fault system on the northwestern margin (Figures 4, 6).
Full-graben systems are not encountered elsewhere in the western rift valley. The north and middle depressions of south basin have good hydrocarbon potential. Abstract Recent high-resolution airborne gravity data taken over the South Yellow Sea and its western onshore–offshore transition zone, combined with ground gravity data taken over the onshore area (Subei Basin), China, show that the South Basin of the South Yellow Sea and the Subei Basin correspond to the same Cited by: Gravity modelling indicates a thinned continental crust underneath the Sarawak shelf and slope and supports the seismic and well data interpretation.
There is a probable presence of an overthrust wedge beneath the Sarawak shelf, which could be interpreted as a sliver of the Rajang Group accretionary by: The geological development of Panama is a consequence of the relative motions of the North and South American continental plates and four oceanic plates over the past million years, and is a part of the larger story of the tectonic development of the Caribbean basin and Central by: DSDP/ODP Hole B is located in the Panama Basin, eastern Pacific ocean, km south of the Costa Rica Rift, which is a km-long east-west trending segment of.
