Modeling cryogenic mud volcanism on Pluto

Journal of Volcanology and Geothermal Research, 2020
Abstract Subsurface ice cryofluids and ice interactions with ammonia for cryovolcanic materials give the potential ingredients for the formation of mud volcanoes on Pluto. In order to constrain the possible morphology from images acquired by the New Horizons spacecraft, we have modeled the formation of mud volcanoes, isostatic layers of ice overlain ...

Modern Ideas About Mud Volcanism

2020
According to the authors’ opinion, formed on the basis of numerous definitions proposed by many researchers as well as the recovery and analysis of new geological materials, mud volcanism represents one manifestation on the Earth’s surface of local gas flows emanating from deep hydrocarbon sources.

Fluid-dynamic modeling of mud volcanism

Russian Geology and Geophysics, 2011
Abstract The eruptive behavior of mud volcanoes has been explored in several forward and inversion models. The forward models, based on classical continuum-mechanics, simulate the non-stationary processes of gas seepage and two-phase gas-mud flow through the conduit of a mud volcano, as well as the quasi-stationary gas frontal drive that

New Data on Mud Volcanism in the Arctic on the Yamal Peninsula

Doklady Earth Sciences, 2023
A wide range of geological and geophysical methods was carried out on the Yamal Peninsula in the Arctic in the period 2014–2022. The results were analyzed together with data from remote sensing of the Earth. Fundamentally new data on the gas-dynamic mechanisms of dangerous processes in permafrost have been obtained. These data included catastrophic gas

Serpentinite Mud Volcanism: Observations, Processes, and Implications

Annual Review of Marine Science, 2012
Large serpentinite mud volcanoes form on the overriding plate of the Mariana subduction zone. Fluids from the descending plate hydrate (serpentinize) the forearc mantle and enable serpentinite muds to rise along faults to the seafloor. The seamounts are direct windows into subduction processes at depths far too deep to be accessed by any known ...

On the probability of cryogenic mud volcanism on Titan

Solar System Research, 2008
Juxtaposing images of the surface of Titan made by the Huygens probe and photos of the mud volcano region on Earth (the Taman peninsula, the Caucasus) reveals similar geomorphologic features. This has led us to suggest the existence of cryogenic mud-volcanic activity on Titan.

Shallow-rooted mud volcanism in Lake Baikal

Marine and Petroleum Geology, 2019
Abstract Lake Baikal is the only freshwater basin containing sediments with gas hydrate accumulations, some of which are associated with mud volcano activity. Twenty-two mud volcanoes have already been identified in different areas of Lake Baikal, but the formation process and source depth remained unknown due to a lack of conclusive evidences.

Mud Volcanoes, Their Distribution Regularities and Genesis: Communication 1. Mud Volcanic Provinces and Morphology of Mud Volcanoes

Lithology and Mineral Resources, 2002
The article discusses regularities in the distribution of mud volcanoes and characterizes most important mud volcanic provinces of the world. A new morphogenetic classification of mud volcanoes substantiated by results of their study in the Crimean–Caucasian and West Turkmenian regions is proposed.

Mud volcanism and mud breccia clasts: how did they reach the surface?

Mud volcanism is a geological phenomenon broadly diffused in active and passive tectonic settings and it is typically associated with petroleum systems. The mechanisms driving this process are the overpressure resulting from the generation of hydrocarbons at depth combined with the gravitative instability (e.g., shale buoyancy and density inversion) of

Mud generation from stratified sediments in a context of mud volcanism : the role of gas

Génération de boue à partir de sédiments stratifiés dans un contexte de volcanisme de boue : le rôle du gaz Ce manuscrit étudie le rôle du gaz dans les processus de génération de boue en se concentrant sur un jeu de donnée riche et pluridisciplinaire du volcan de boue actif d’Absheron (VBA) dans le Bassin sud caspien.
