The origin of mud volcanoes [PDF]

Geology and Mineral Resources of World Ocean, 2019
The article shows that the immersion of clay strata in the region of high temperatures and pressures creates two fluid dynamic zones. In the upper zone, clay porosity decreases, and sedimentation and diagenetic waters are released; these elision phenomena create abnormal reservoir pressure in reservoir layers and give rise to a complex system of fluid ...

Two-End-Member Mixing in the Fluids Emitted From Mud Volcano Lei-Gong-Huo, Eastern Taiwan: Evidence From Sr Isotopes

Frontiers in Earth Science, 2022
Mud volcano is one of the most important conduits for deep seated materials to migrate upward in sedimentary basins, convergent margins, and subduction zones.

Mud Volcanoes

, 2010
Mud volcanoes are frequently encountered geo-structures at active and passive continental margins. In contrast to magmatic volcanoes, mud volcanoes are marine or terrestrial, topographic elevations built from vertically rising fluidized mud or mud breccia. Commonly, these structures have a crater, hummocky rime and caldera.

Mud Volcanoes [PDF]

, 2009
AbstractThe eruption of mud and magma can be influenced by earthquakes and reports date back more than 2000 years. Dozens of examples of eruptions have now been documented in response to both static and dynamic stresses from earthquakes. Already erupting systems are most sensitive to earthquakes compared to initiating new eruptions.

Mud volcano dynamics in Azerbaijan: the overlooked role of creeping mud flows in landscape evolution [PDF]

Earth Surface Dynamics
Azerbaijan hosts the world's highest concentration of mud volcanoes (MVs) on Earth, including some of the largest edifices that produce kilometre-scale mud breccia flows.

"NOVOSIBIRSK" MUD VOLCANO AND EVIDENCE OF ITS ACTIVATIONS (LAKE BAIKAL)

Геодинамика и тектонофизика
An integrated study of mud volcanoes in the World Ocean is important for making assessment of potential geological-ecological disasters caused by rapid large-volume gas discharge into the water column and mud volcano eruptions at the bottom. The study of

Electric Discharge in Erupting Mud

Geophysical Research Letters, 2022
Self‐ignition during the explosive eruption of mud volcanoes can create flames that in some cases reach heights that exceed hundreds of meters. To study the controls on electrical discharge in natural mud, we performed laboratory experiments using a ...

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs

Deep Underground Science and Engineering, EarlyView.
A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Thessaloniki Mud Volcano, the Shallowest Gas Hydrate-Bearing Mud Volcano in the Anaximander Mountains, Eastern Mediterranean [PDF]

Journal of Geological Research, 2011
A detailed multibeam survey and the subsequent gravity coring carried out in the Anaximander Mountains, Eastern Mediterranean, detected a new active gas hydrate-bearing mud volcano (MV) that was named Thessaloniki. It is outlined by the 1315 m bathymetric contour, is 1.67 km2 in area, and has a summit depth of 1260 m.
