Permo-carboniferous Magmatism and Rifting in Europe
In some instances pyroxenite xenoliths accompany mantle peridotite xenoliths;
however, at several localities from the SMV to the Orkneys, peridotites are
missing and the xeno- lith population is overwhelmingly pyroxenitic, although it
includes ...

Geological Survey of Canada, Open File 2659
Any rock with 10%<MgO<20% is classified as a pyroxenitic komatiite (the third
group). This group includes only several spinifex and flow top breccia samples.
Samples collected from spinifex zones are termed "spinifex textured komatiite ...

A suitable compromise was found by allowing two categories of pyroxenitic
garnets. Pyroxenitic garnets similar to, but richer in Fe than moderate- to low-Cr
G9 garnets are designated "G5" in the updated scheme, although the original
term ...

... of 478 H-3/— 2 and 480 ± 2 Ma, which were interpreted as crystallization ages
by Whitehead et al. (2000). Hypabyssal fades Two types of hypabyssal facies
rocks occur above the Gabbroic and Pyroxenitic Zones: dyke swarms and
breccias.

Cenozoic Volcanism in the Mediterranean Area
Direct subduction of lower-crustal slices could represent an alternative
mechanism to recycle granulitic- pyroxenitic-eclogitic lithotypes to great depths.
Stochastic sampling of such heterogeneities (detached ancient lower crust +
lithospheric ...

Phosphate Deposits of the World: Volume 2, Phosphate Rock ...
Dykes and veins of syenite intrude the pyroxenitic members of the Complex.
There appear to be no structural or tectonic controls to the emplacement of the
main body or the syenites. In reviewing the distribution of South African
carbonatites, ...

As far back as 1979, Augustithis pointed out that dunitic rocks are mainly
characterized by the presence of chromospinel and that pyroxenitic rocks with
magnetite or titanomagnetite exist where in addition to the prevalence of Fe
spinels ...

Precambrian Ophiolites and Related Rocks
In the main part it consists of a well preserved, lensoid pyroxenitic suite that
grades into a crudely layered to a massive melano- to mesogabbroic
assemblage containing frequent serpentinite layers and some re- stricted
anorthositic lenses.

Magmatism in Relation to Diverse Tectonic Settings
Megascopically peridotite/pyroxenite and layered pyroxenitic transitions (M=90
and transitional to M=70) range from medium- to very coarse-grained
melanocratic types. The specimens from Jind Baba ki Madhi are relatively
coarser compared ...

Metasomatism in Oceanic and Continental Lithospheric Mantle
SCS sub-alkaline pyroxenitic xenoliths taken from Orejana et al. (2006). The
curve joining small open diamonds represents a simple mixing model illustrating
the probable influence of the infiltration of alkaline magmas (metasomatism and ...
