This makes the it more like a pyroxenite, than the typical angrite which is similar to a basalt.
It is a special type of pyroxenite.
Its igneous rock consists mostly of pyroxenite and gabbro.
This magma produced the layered pyroxenite dunite in the ultramafic area.
For the igneous rock type "websterite", see pyroxenite.
The upper third is massive bronzite pyroxenite.
Rock types include picrite, peridotite, dunite, pyroxenite, gabbro and granophyre.
The igneous rock is mostly mafic with much gabbro, essexite, and a titanium-rich pyroxenite.
Source rocks for the partial melts probably include both peridotite and pyroxenite (e.g., Sobolev et al., 2007).
The parent rock of this banded variety most likely was a pyroxenite enclosing cumulate layers of dunite.
It occurs in pegmatites in a pyroxenite intrusion as crystals in miarolitic cavities.
They consist of lherzolite, harzburgite, wehrlite, dunite, websterite and garnet composed pyroxenite.
Cumulate dunite may also be found in ophiolite complexes, associated with layers of wehrlite, pyroxenite, and gabbro.
The eclogite melt may then react with enclosing peridotite to produce pyroxenite, which in turn melts to produce basalt.
The igneous material is composed almost entirely of mafic and ultramafic rock such as gabbro and olivine-bearing pyroxenite.
Several northeast-trending deformation zones intersect pyroxenite of a mafic sill in northwest Strathy Township.
The pyroxenite outcrops are dark and massive and include discontinuous calc-silicate bands, some of brown mica and others with calcite.
Enstatite, close to EnFs in composition, is an essential mineral in typical peridotite and pyroxenite of the Earth's mantle.
Some of the minerals found in this region are dolomite, limestone, gabbro, quartzite, pyroxenite, manganese and iron ores and metabasalt.
The ultramafic zone is composed of a lower peridotite member consisting of alternating dunite, chromitite, harzburgite and bronzite pyroxenite.
Small but commercially important quantities are also found in pentlandite extracted from Sudbury, Ontario and in pyroxenite deposits in South Africa.
A layered intrusion composed of diorite, pyroxenite, gabbro and anorthositic gabbro has been found in northwestern Strathy Township.
Bronzitite, a pyroxenite of bronzite composition, is noted in the cumulate rocks of the Stillwater igneous complex of Montana.
They lie in basic rocks such as gabbro and pyroxenite, and these in the neighborhood of the veins have been extensively scapolitized, like the spotted gabbros of Norway.
