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.

How Cratonic Roots Survive With Weak Mid‐Lithosphere Discontinuities

open access: yesGeophysical Research Letters
The stability of cratons has long been attributed to their neutral buoyancy and strong roots. However, recent seismic studies have revealed widespread mid‐lithospheric discontinuities (MLDs) within cratonic roots.

Evaluation of Contextual and Game-Based Training for Phishing Detection

open access: yesFuture Internet, 2022
Cybersecurity is a pressing matter, and a lot of the responsibility for cybersecurity is put on the individual user. The individual user is expected to engage in secure behavior by selecting good passwords, identifying malicious emails, and more. Typical

Craton Destruction Induced by Drastic Drops in Lithospheric Mantle Viscosity

open access: yesEarth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract The disruption of the mantle roots of cratons is common after cratonization. Craton destruction, which is characterized by severe lithospheric thinning, extensive thrust and extensional deformation, basin filling, and intense thermal activities, is relatively rare and is generally attributed to intensely reduced viscosity contrasts between the

Characterizing Peridotite Xenoliths From Southern Vietnam: Insight Into the Underlying Lithospheric Mantle

open access: yesGeochemistry, Geophysics, Geosystems, 2023
We present data for lithospheric mantle xenoliths sampled from two alkali basalts in south‐central Vietnam, Pleiku and Xuan Loc, including fertile spinel peridotites.

XENOLITHS OF POLYMICTIC BRECCIAS FROM KIMBERLITES OF THE YAKUTIAN DIAMONDIFEROUS PROVINCE

open access: yesГеодинамика и тектонофизика, 2022
The polymictic breccias, extremely rare mantle conglomerates being the fragments of rocks and large mantle minerals cemented with fine-grained mass have been long provoking interest of petrologists worldwide.

Carbonatite Versus Silicate Melt Metasomatism Impacts Grain Scale 87Sr/86Sr and 143Nd/144Nd Heterogeneity in Polynesian Mantle Peridotite Xenoliths

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The Earth's upper mantle is isotopically heterogeneous over large lengthscales, but the lower limit of these heterogeneities is not well quantified. Grain scale trace elemental variability has been observed in mantle peridotites, which suggests that ...

Hydration State and Rheologic Stratification of the Lithospheric Mantle Beneath the North Anatolian Fault, Turkey

open access: yesGeochemistry, Geophysics, Geosystems, 2023
We present constraints on the hydration state and rheology of the lithospheric mantle beneath the North Anatolian fault zone (NAFZ). Peridotite xenoliths from the Biyikali and Çorlu volcanic centers record deformational microstructures consistent with ...

POSSIBLE EVIDENCE FOR THE EXISTENCE OF VOLCANOGENIC MAGMATISM IN THE SINYAYA RIVER BASIN AT THE SOUTHERN FLANK OF THE VILYUI SYNECLISE

open access: yesГеодинамика и тектонофизика, 2023
The results of different-extension geological survey, exploration and thematic work methods show that the Vilyui syneclise is relatively amagmatic. However, the recent factual evidence in this region indicates the occurrence of magmatism of a different ...
