3D seismic expression of km-scale fluid escape pipes from offshore Namibia

Abstract:

This paper documents a large number of large km-scale fluid escape pipes with complex seismic expression and a diatreme-like geometry from the mapping of a 3D seismic survey, offshore Namibia. These pipes are crudely cylindrical, but occasionally have steep conical geometry either narrowing upwards or downwards. They are generally ovoid in planform and their ellipticity varies with pipe height. Vertical dimensions range from ca. 100 to >1000 m and diameters range between 50 and 600 m. The ...
