Ophiolites in Earth History
Subordinately, subhedral spinel can be found among or within olivine, whereas
xenomorphic spinel (0.5-1 mm) is locally placed at the rim of tabular
orthopyroxene. The association formed by relics of spinel, plagioclase ±
orthopyroxene is ...

Rock-Forming Minerals: Orthosilicates, Volume 1A:
volume by volume replacement (with excess oxygen) Ambler and Ashley
calculated the changes in MgO, ' FeO and Si62 wt. per cent for the olivine-
symplectite reaction: 1 vol. olivine, Fo63 .8 -* 0-57 vol. orthopyroxene, En6g + 0-
43 vol.
William Alexander Deer, Robert Andrew Howie, J. Zussman, 1982
The partition of Ni between orthopyroxene and olivine, in the prehistoric
Makaopuhi Lava Lake, Hawaii, has been determined by Evans (1969), and
shows that the poikilitic orthopyroxene probably crystallized in exchange
equilibrium with the ...

Precambrian Geology of the Tobacco Root Mountains, Montana
It is evident from this diagram that these rocks contain substantial amounts of
normative orthopyroxene (see also Fig. 8). Indeed, we conclude that the
protoliths of the Tobacco Root meta-ultramafic rocks were cumulates rich in
orthopyroxene, ...
5
Deformation and Grain-size Evolution of
Orthopyroxene in the ...
Processes related to the grain-size evolution of orthopyroxene at upper mantle conditions are investigated from experimental and observational perspectives.
Philip Alexander Skemer, 2007

Phase Diagrams for Geoscientists: An Atlas of the Earth's ...
sitions have slightly higher Ca contents than those determined by Biggar (1988),
but the orthopyroxene to protopyroxene + clinopyroxene boundary is in
agreement (Fig. 4.2). The calculated temperature-composition phase diagrams
for the ...

Magmatic Sulfide Deposits: Geology, Geochemistry and Exploration
Anhedral. subequant; also as subrounded; resorbed grains 0.2 to 1 mm
poikilitically enclosed within orthopyroxene and plagioclase 1-3 mm. Tabular;
coronas of orthopyroxene in places surround olivine enclosed in plagioclase <
0.5 mm.

Planetary Petrology and Geochemistry: The Lawrence A. Taylor ...
Ni in Olivine An origin for orthopyroxene-rich cratonic peri- dotites by
metasomatism of olivine-rich oceanic peridotites has been proposed by a
number of authors (Kesson and Ringwood, 1989; Kelemen et al., 1992, 1997;
Rudnick et al., 1994; ...
Lawrence A. Taylor, Gregory A. Snyder, Clive R. Neal, 1999
Two and three zone coronas, orthopyroxene-(pargasite-spinel symplectite) and
orthopyroxene-hornblende-garnet are present in olivine gabbros of the
Niquelandia layer complex, central Goias, Brazil (Fornoni et al. 1989). Mass
balance ...

High-Temperature Metamorphism and Crustal Anatexis
garnet and clinopyroxene to symplectitic orthopyroxene and plagioclase ( +
magnetite, not shown in Fig. 10.6), the three-phase field moves towards the Fe-
side, leading to an Fe-rich orthopyroxene (Sympl. in Fig. 10.6), a slightly Fe-richer
