Heat transport in serpentinites

Tectonophysics, 2003
Abstract The thermal transport properties thermal conductivity and thermal diffusivity were examined for a variety of serpentinites as a function of temperature at ambient pressure. The thermal transport properties of serpentinites show an extraordinary behavior.

Serpentinite and the search for life beyond Earth

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020
Hydrogen from serpentinization is a source of chemical energy for some life forms on Earth. It is a potential fuel for life in the subsurface of Mars and in the icy ocean worlds in the outer solar system. Serpentinization is also implicated in life’s origin.

Tectonic significance of serpentinites

Tectonophysics, 2015
At plate boundaries, where deformation is localized along centimetre- to kilometre-scale shear zones, the influence of serpentinite on tectonic processes is linked to its unique rheological properties. In this paper wereview the physical properties of serpentinites and their role in tectonic processes.

Digger Pine Seedling Response to Serpentinite and Non‐Serpentinite Soil

Ecology, 1965
Seedlings were grown from 17 seed samples collected throughout the natural range of Pinus sabiniana in California. Five collections came from soils derived from ultra—basic serpentinized rock. The seedlings were grown in a greenhouse in cans filled with two different soils. One series of 36 seedlings per sample grew in a fertile, loamy sand forest soil.

Serpentinites, Hydrogen, and Life

Elements, 2013
The process of serpentinization creates strongly reducing conditions and produces fluids that are highly enriched in molecular hydrogen and methane. Some microorganisms are able to exploit these compounds to gain metabolic energy and to generate biomass, leading to the development of biological communities based on chemical energy rather than ...

Alpine‐type serpentinites from the Auckland Province—II. North Auckland serpentinites

Journal of the Royal Society of New Zealand, 1973
Abstract Eighty discrete lopolithic‐shaped bodies of serpentinite ranging from 350 m 3 to 24 000 m 8 in size are found in North Auckland, south of Whangarei and east of Hatherton and Sibson's (1970) junction anomaly, within the Onerahi

Serpentinites, Peridotites, and Seismology

International Geology Review, 2004
Understanding the physical properties of ultramafic rocks is important for evaluating the wide variety of petrologic models for the Earth's upper mantle and lower oceanic crust.

Serpentinite: What, Why, Where?

Elements, 2013
Rock-forming serpentine minerals form flat, cylindrical, and corrugated crystal microstructures, which reflect energetically efficient layering of alternate tetrahedral and octahedral sheets. Serpentinization of peridotite involves internal buffering of the pore fluid, reduction of oxygen fugacity, and partial oxidation of Fe 2+ to Fe 3+ .

Hydrochloric attack of serpentinites: Mg2+ leaching from serpentinites.

Magnesium research, 2001
This paper presents the hydrochloric attack of serpentinites. Romanian serpentinites are part of the Danubian crystalline complex. These serpentinites contain mineral serpentine (magnesium silicate) and a small amount of other minerals along with calcium, iron, aluminium, nickel, cobalt, chrome and manganese.
