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 ...

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, ...

Ni in Olivine An origin for orthopyroxene-rich cratonic peri- dotites by
metasomatism of olivine-rich oceanic peridotites has been proposed by a

Two and three zone coronas, orthopyroxene-(pargasite-spinel symplectite) and
