Permian Large Igneous Provinces and Their Paleoenvironmental Effects

open access: yesGeophysical Monograph Series, Page 417-434., 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.

Neutrosophic Functions Of The Joint Roughness Coefficient And The Shear Strength: A Case Study From The Pyroclastic Rock Mass In Shaoxing City, China [PDF]

open access: green, 2016
Many studies have been carried out to investigate the scale effect on the shear behavior of rock joints. However, existing methods are difficult to determinate the joint roughness coefficient (JRC) and the shear strength of rock joints with incomplete ...

The Basal Friction Coefficient of Granular Flows With and Without Excess Pore Pressure: Implications for Pyroclastic Density Currents, Water‐Rich Debris Flows, and Rock and Submarine Avalanches

open access: greenJournal of Geophysical Research: Solid Earth, 2020
Numerous large‐scale geophysical flows propagate with low‐apparent basal friction coefficients, but the source of such phenomenology is poorly known. Motivated by scarce basal friction data from natural flows, we use numerical methods to investigate the ...

Formation Mechanism and Prediction Method for the Permian Fused Breccia Tuff Reservoir, Wuxia Region, Junggar Basin

open access: yesGeofluids, 2021
Fused breccia tuff occurs globally, but its formation mechanism is very controversial. Volcanic reservoirs have developed at the bottom of the Permian Fengcheng Formation in the Wuxia region of the Junggar Basin, and here, the lithology is fused breccia ...

A thermodynamical model for rainfall-triggered volcanic dome collapse [PDF]

open access: yes, 2004
Dome-forming volcanic eruptions typically involve the slow extrusion of viscous lava onto a steep-sided volcano punctuated by collapse and the generation of hazardous pyroclastic flows.

The Kummitsoiva komatiite complex and its satellites in northern Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1983
The Kummitsoiva komatiite complex and its satellites, regarded either as Archean or Proterozoic in age, consist principally of amphibole- chlorite rocks corresponding chemically to basaltic komatiite of the Geluk type in South Africa.
