Petrostructural typification of the kanskiy greenstone belt ultramafites [PDF]

, 2007
Two types of ultramafites have been distinguished in the Kanskiy greenstone belt (NW of the Eastern Sayan): magmatic of the dunite-wehrlite-picrite composition and restitic of the dunite-harzburgite composition.

Whole-rock geochemical analyses of serpentinized harzburgites from ODP Site 209-1270

, 2010
Small-scale shear zones are present in drillcore samples of abyssal peridotites from the Mid-Atlantic ridge at 15°20'N (Ocean Drilling Program Leg 209). The shear zones act as pathways for both evolved melts and hydrothermal fluids.

AMPHIBOLE IN ULTRA-DEPLETED PERIDOTITES FROM THE HOROKANAI OPHIOLITE, HOKKAIDO, JAPAN:BONINITE MELT TRAPPED IN THE MANTLE WEDGE

Ultra-depleted peridotites have been reported from the mantle sections of a number of ophiolitic complexes (e.g., Papua New Guinea and New Caledo-nia).

Compositional variations as a result of partial melting and melt-peridotite interaction in an upper mantle section from the Ortaca Area, southwestern Turkey

, 2007
The bulk composition (major and trace elements) and the composition of minerals in peridotites of the Ortaca area, southwestern Turkey, have been investigated to understand the processes controlling lithological and compositional variations in the ...

Melt evolution in subarc mantle: Evidence from heating experiments on spinel-hosted melt inclusions in peridotite xenoliths from the andesitic Avacha volcano (Kamchatka, Russia)

, 2016
Glass-bearing inclusions hosted by Cr-spinel in harzburgite xenoliths from Avacha are grouped based on homogenization temperatures and daughter minerals into high-T (1,200°C; opx + cpx), intermediate (900-1,100°C; cpx ± amph), and low-T (900°C ...

Thermodynamic Predictions of Hydrogen Generation during the Serpentinization of Harzburgite with Seawater-derived Brines

The Planetary Science Journal
Salty aqueous solutions (brines) occur on Earth and may be prevalent elsewhere. Serpentinization represents a family of geochemical reactions where the hydration of olivine-rich rocks can release aqueous hydrogen, H _2(aq) , as a byproduct, and hydrogen ...

Evidence for the Suprasubduction Origin of Mantle Section Rocks of Voykar Ophiolite, Polar Urals

, 2009
We studied mantle rocks in the northern part of the Voykar Ophiolite where the thickness of peridotite sections reaches 6 km. Harzburgite depleted to a variable degree in basaltic material predominates among the rocks.

Ocean Drilling Program Scientific Results Volume 147

, 1996
Surface sediments from Holes 894D, 894E, and 895A of ODP Leg 147 were examined for chromian spinel and other detrital minerals in order to determine the source rocks of the Hess Deep sediments.
