The conversion of biogenic silica (opal-A) to opal-CT (cristobalite and tridymite) in
biosiliceous sediment causes increased rates of water expulsion because of the reduction in …

The Menes caldera is a fault-controlled depression (~ 8 km in diameter) at~ 3,000 m water
depth in the western province of the Nile deep-sea fan off NW Egypt, comprising seven mud …

Abstract The Nirano Salse, known since the Roman Times, are one of the most beautiful and
scenic mud volcanoes areas of Italy with thousands of visitors every year. In this work, we …

This paper presents a structural and stratigraphic analysis of the foreland-fold-belt of the
Eastern Venezuelan Basin and the main conclusions about shale tectonic mechanisms in …

High-resolution single channel and multichannel seismic reflection profiles and multibeam
bathymetric and backscatter data collected during several cruises over the period 1999 to …

Using 3D seismic data, we document the subsurface architecture of a cluster of 3 mud
volcanoes located on the upper continental slope offshore Nigeria. In a background of gently …

Circular depressions bounded by inward-dipping faults found at the upper terminations of
large mud volcano systems (> 500 m diameter) are termed 'mud volcano summit calderas' …

The role of mud volcanism on subsurface fluid migration and material cycling has long been
debated. Here we compile the heights and radii of offshore mud volcanoes and estimate a …

Using three-dimensional (3D) seismic data, we establish a simple model for the
development of vertical fluid flow pipes in the deepwater western Niger Delta. We analyse …

Post-rift magmatism along continental margins is usually focused on highly stretched basins
or aborted rifts. Adjacent microplates with relatively thick lithosphere are not expected to …
