Weakening of Peridotite Sheared at Hydrothermal Conditions

open access: yesGeochemistry, Geophysics, Geosystems, 2021
We conducted triaxial friction tests at hydrothermal conditions (25°C–350°C) on gouges of peridotite and its principal mineral constituents olivine and orthopyroxene. Pore‐fluid chemistry was varied by the use of peridotite, granite, or quartzite driving

The Role of Peridotite for Oceanic Volcanism

open access: yesGeochemistry, Geophysics, Geosystems
The complementary products of oceanic crust formation are compositionally variable melt‐depleted peridotites. Together with the oceanic crust, the melt‐depleted peridotites are continuously recycled back into the mantle.

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.

Braided peridotite sills and metasomatism in the Rum Layered Suite, Scotland [PDF]

open access: yes, 2020
The Rum Eastern Layered Intrusion (ELI; Scotland) is an open-system layered intrusion constructed of 16 macro-rhythmic units. Each of the macro-rhythmic units consists of a peridotite base and a troctolite (+/- gabbro) top, previously attributed to the ...

The Influence of the Mineralogical Composition of Ultramafic Rocks on Their Engineering Performance: A Case Study from the Veria-Naousa and Gerania Ophiolite Complexes (Greece)

open access: yesGeosciences, 2018
This case study investigates the influence of the mineralogical composition of ultramafic rocks derived from two ophiolite complexes from Greece (Veria-Naousa and Gerania) on their mechanical, physical and physicochemical properties.

Water in Hawaiian peridotite minerals: A case for a dry metasomatized oceanic mantle lithosphere

open access: yesGeochemistry, Geophysics, Geosystems, 2015
The distribution of water concentrations in the oceanic upper mantle has drastic influence on its melting, rheology, and electrical and thermal conductivities and yet is primarily known indirectly from analyses of OIB and MORB.
