Tensile Strength of Serpentinized Harzburgite
58th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: Ultramafic rocks play an active role in geologic processes including the carbon cycle and serpentinization reactions. Many of these processes accompany mineral transformations that result in volume increase of the product phase (e.g. serpentinization, carbonation).

Thermoelastic and thermodynamic properties of harzburgite—An upper mantle rock
Journal of Physics and Chemistry of Solids, 2008Abstract A number of thermoelastic and thermodynamic properties such as compressibilities, specific heat ratio, specific heat capacities, Gruneisen parameters, Debye temperature, the melting temperature, and their dependence on temperature and pressure have been obtained for the harzburgite rock of Oman ophiolite suite. Debye temperature Θ D

Oman Ophiolite: The Harzburgite Ophiolite Type
1989Although the first detailed report on the Oman ophiolite is recent (Reinhardt, 1969), it is now one of the best studied complexes and is often considered to be the best example of ophiolites in the world. It is indeed the largest, with a crescent-shaped extension over 500 km in length and 50–100 km in width (fig.3.1 and 3.2).

Formation of harzburgite by pervasive melt/rock reaction in the upper mantle
Nature, 1992Many mantle peridotite samples are too rich in Si02 (in the form of orthopyroxene) and have ratios of light to heavy rare earth elements that are too high to be consistent with an origin as the residuum of partial melting of the primitive mantle. Trace element studies of melt/rock reaction zones in the Trinity peridotite provide evidence for reaction ...

Intermediate-depth earthquakes linked to localized heating in dunite and harzburgite
Nature Geoscience, 2017Earthquakes can occur at great depths in the Earth, within subducting tectonic plates. Deformation experiments suggest these deep earthquakes can be triggered by localized heating of the slabs under high pressures.

“Eclogite” in the Ballantrae Complex: a garnet-clinopyroxenite segregation in mantle harzburgite?
Scottish Journal of Geology, 1984Synopsis The well-known occurrence of eclogite within the Ballantrae complex at Knockormal is enigmatic and unique within the paratectonic Caledonides of the British Isles. Although the “outcrop” originally described is demonstrably a large loose block, garnet-pyroxenite uncovered in situ in a temporary ...

Serpentinisation of harzburgites from the alpine peridotite belt of Southwest Turkey
Chemical Geology, 1970Abstract Analyses are presented for some harzburgites from southwest Turkey. These ultramafics, classed broadly as peridotites, show wide variation in the degree of alteration from fresh to fully serpentinised. A technique is described to recast the analyses into a realistic “normative” mineralogy.

Permeability of Serpentinized Harzburgite and its Implications on Mineral Carbon Storage
58th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: Storage of anthropogenic CO2 as permanent carbonate minerals has emerged as a promising method for control of carbon dioxide. One approach consists of injecting low-pH, CO2-rich water in ultramafic rock that serves as a buffering medium.
