Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 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.

Diapirism and topography [PDF]

open access: yesGeophysical Journal International, 1992
SUMMARY A new numerical technique using markers and a deformable Lagrangian mesh is used to study the deformation of the surface above a rising diapir. This method allows modelling of a free-surface boundary in a self-consistent way. The method makes it possible to investigate many different problems with non-regular geometry.

Tracking the Serpentinite Feet of the Mediterranean Salt Giant

open access: yesGeosciences, 2018
Interpretation of seismic profiles and results of scientific drillings in the Mediterranean subseafloor provided indication of gigantic salt deposits which rarely crop out on land, such as in Sicily.

Quantifying Diapir Ascent Velocities in Power‐Law Viscous Rock Under Far‐Field Stress: Integrating Analytical Estimates, 3D Numerical Calculations and Geodynamic Applications

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Diapirism is crucial for heat and mass transfer in many geodynamic processes. Understanding diapir ascent velocity is vital for assessing its significance in various geodynamic settings.

Salt structures from inversion of residual gravity anomalies: application in Santos Basin, Brazil

open access: yesBrazilian Journal of Geology, 2019
The Santos Basin, with an area of about 350.000 km 2 , is the largest salt basin of the South Atlantic, and due to its high economic hydrocarbon potential, it is a recurrent theme in scientific studies.

Geophysical-Geotechnical Characterization of Mud Volcanoes in Cartagena Colombia

open access: yesGeosciences
In this research, the mud diapirism phenomenon in the Membrillal sector in Cartagena is characterized to analyze its spatiotemporal evolution. The goal is to geomorphologically, geotechnically, and geologically characterize the area to zone regions with ...

RESEARCH ON THE VULNERABILITY OF SOMEș MIC MEADOW IN TERMS OF HYDROGEOLOGICAL

open access: yesAgricultura, 2013
The area between Cluj-Napoca and Apahida consists of miocene and quaternary deposits. Miocene (tortonian) is affected by salty diapirism manifested by salt water, which influences the water chemistry of quaternary deposits.

Formation of the Naxos nested domes and crustal differentiation by convection and diapirism

open access: yesBSGF - Earth Sciences Bulletin
The Naxos dome, in the middle of the Aegean domain, exposes the former root of the Alpine orogenic belt and represents a key natural example to investigate the development of gravitational instabilities during orogenic evolution and their impact on ...

Petrochronology of Alkaline Intrusive Magmatism in the Central High‐Atlas (Morocco) and Relationships With Jurassic Salt Diapirism

open access: yesGeochemistry, Geophysics, Geosystems
A striking feature of the Imilchil alkaline province, in the Moroccan Central High Atlas, is the close association of magmatic intrusions with Triassic sediments exhumed by diapirism. This study reports field, petrographic, geochemical and Sr‐Nd isotopic
