Architecture and image characteristics of a normal fault - Inner Moray Firth Interpretation

VSA Author: Rob Butler
Date Created: 2015-01-28

These interpretations display a correlation of units across the fault zone - which has synthetic splays and an offset relay structure at depth. The growth strata are chiefly of upper Jurassic in age - with the deepest identified unit par of the middle Jurassic (locally) pre-rift stratigraphy. The annotations identify some "typical" characteristics of faults imaged in 2D seismic data. ...

Date Created: 2016-10-17

These vintage seismic images were acquired by Compania General de Geofisica from the external zones of the Betics fold and thrust belt, southern Spain. They and other seismic lines from the area, together with acquisition and processing information, are publicly available at http://info.igme.es/infogeof/ provided by the Direccion General de la Energia, Spanish Ministry of Energy and I...

DRUM filtered 2 Regional Project

VSA Author: Taija Torvela
Scenes: 0
Interpretations: 0
Date Created: 2016-05-02

The original seismic is filtered with 8x8 (trace x sample) dip-steered median filter of Opendtect with a maximum seismic dip of c. 40 degrees, this reduces 1D noise and also removes some steep coherent noise while enhancing signal continuity. This filtered seismic is then overlain with the cosine of phase attribute of the dip-steered data, in order to enhance the signal geometries fur...

An interpretation of the detail of the line TEPP00-128, showing mass wasting transition at the Somnath Ridge NW escarpment (Fig. 12D in Calves et al. 2011; see the main VSA survey docs & links).

Variance extraction at the base of the post-avulsion channel. Notice the downdip increase in sinuosity due to underlying bathymetric anomalies (see cross-sections). A more detailed explanation can be found in Ortiz-Karpf et al (2015). The link to the paper can be found in the docs and links tab.

DRUM filtered 3 Regional Project

Date Created: 2016-05-02

The original seismic is first filtered with 8x8 (trace x sample) dip-steered median filter of Opendtect with a maximum seismic dip of c. 40 degrees, this reduces 1D noise and removes some steep coherent noise too while enhancing signal continuity. The dip-steered seismic is then overlain with the energy attribute to bring out the strong reflections whilst muting some of the signal bet...

Patch-reef outlier detail Scene

VSA Author: Henry Posamentier
Interpretations: 0
Date Created: 2010-06-06

A) Plan and B) perspective views of seismic amplitude map of an outlier buildup in the northern part of the study area. Debris aprons expressed as amplitude brights (reds and yellows) extending 1–2 km away from this buildup characterize the adjacent basin-floor areas. Plumes of amplitude brights (possible calciturbidites) are observed to emanate from the mouths of platform channels (...

Seismic stratigraphy exercise Interpretation

VSA Author: Julien Moreau
Date Created: 2013-09-12

Correction of a seismic interpretation exercise I gave. The interpretation is uniquely based on reflection termination picking which indicate bounding surfaces. No model is involved. Colours between two successive bounding surfaces have no genetic meaning they only give a sort of chronology through the repetition of a colour cycle (blue, pink, green,yellow) . The objective of the exer...

Minibasin above mobile Messinian salt , floor of Ionian Sea Scene

VSA Author: Rob Butler
Interpretations: 1
Date Created: 2008-02-16

Extensional minibasin formed above a mobile substrate (Messinian evaporites?) on the floor of the Ionian Sea. The interpretation here follows a model of extensional flow in the underlying Messinian evaporires. Alternatively the faulting and basin may couple with active basement faulting in the Ionian lithosphere.

Date Created: 2015-03-20

Perspective view of a combined variance and amplitude extraction at the base of the post-avulsion channel, overlain on a variance extraction at the MTC top. Following the avulsion a new channel conduit evolved. Its geometry and trajectory is affected by the underlying megaclasts. A more detailed explanation can be found in Ortiz-Karpf et al (2015). The link to the paper can be found i...
