Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Advective structures of the bottom of lake Natron and its surroundings (Tanzania)

open access: yesРуды и металлы, 2022
In this study we consider the features of the development of weakly lithified bottom sediments and the general structure of lake Natron against the background of its seasonal drying and watering.

Impact of compressional stresses within the South Caspian megadepression upon evolution and oil and gas content of local uplifts

open access: yesВісник Київського національного університету імені Тараса Шевченка. Серія Геологія, 2021
The following structural elements in the South Caspian megadepression (SCMD) have been considered: the interfluve of the Kura and Gabirri, the Absheron and Baku archipelagoes, the Lower Kur depression (LKD) and the Godin massif, that stand out ...

Late Cretaceous mud volcanism in the southwestern Songliao basin records slab rollback of the subducted paleo-Pacific Plate underneath NE China

open access: yesJournal of Asian Earth Sciences: X, 2020
We present a new seismic reflection dataset and use it to characterize fossil mud volcanoes in the southwestern Songliao graben basin in northeastern China. The results reveal a link between mud volcanism and slab rollback along the eastern Asian margin.

Gravity Data Allow to Image the Shallow‐Medium Subsurface Below Mud Volcanoes

open access: yesGeophysical Research Letters, 2023
The debate about the conceptual model of mud volcanoes functioning is still alive in the literature. A large part of the literature focuses on the characterization of the deep reservoir where expelled fluids are expected to originate.

Towards the development of a genetic classification of mud volcanism: An analytical review [PDF]

open access: yesГеосистемы переходных зон
Genetic characteristic of mud volcanism is essential for assessing and predicting mud volcanic hazard, as well as for studying the geo- and fluid dynamics of sedimentary sections.

Numerical modelling of mud volcanoes and their flows using constraints from the Gulf of Cadiz [PDF]

open access: yes, 2003
It is estimated that the total number of submarine mud volcanoes is between 1000 and 100 000. Because many are associated with greenhouse gases, such as methane, it is argued that the global flux of these gases to the atmosphere from the world’s ...

Paleo-environments of sedimentation, mud volcanism and hydrocarbons migration in the South-Caspian basin

open access: yesГеофизический журнал, 2020
One of the problems of oil and gas geology, not finally solved, is a mechanism of hydrocarbons migration and oil and gas deposits formation. It is well known that for production of deposits the presence of not only parent rocks, rocks-collectors and roof-

Velocity Structure Revealing a Likely Mud Volcano off the Dongsha Island, the Northern South China Sea

open access: yesEnergies, 2021
The Dongsha Island (DS) is located in the mid-northern South China Sea continental margin. The waters around it are underlain by the Chaoshan Depression, a relict Mesozoic sedimentary basin, blanketed by thin Cenozoic sediments but populated with ...

RRS "Charles Darwin" Cruise 178, 14 Mar - 11 Apr 2006. 3D seismic acquisition over mud volcanoes in the Gulf of Cadiz and submarine landslides in the Eivissa Channel, western Mediterranean Sea [PDF]

open access: yes, 2006
The major aims of Charles Darwin Cruise 178 were to obtain (i) 3D seismic imagery, video transects and swath bathymetry maps of mud volcanoes in the southern Gulf of Cadiz, (ii) video transects across suspected cold water coral reefs in the Alboran Sea ...
