The three-phase assemblage, orthopyroxene (Wo4)-pigeonite (Wo85)-augite (
Wo25.4) present in the Weiselberg andesite may represent a unique phase
equilibrium, developed at a lower temperature than the two-phase assemblage of
the ...

Essentials of Igneous and Metamorphic Petrology
In the middle of the quadrilateral is the Ca-poor clinopyroxene series, pigeonite.
To understand how the three solution series (augite, pigeonite, and
orthopyroxene) are related, consider relations on a T-X slice across the
quadrilateral (Figure ...

coarse (5-15 )im\ exsolution lamellae of pigeonite oriented into the obtuse angle
a A c (Fig. 15.9}. Host pigeonite may also exsolve comparable coarse lamellae of
augite. On slow cooling, host pigeonite will undergo phase inversion to ...

Studies in Earth and Space Sciences: A Memoir in Honor of ...
Pigeonite has not so far been recorded from probable mantle-derived materials,
although it appears to be stable to at least 20 kb (Brown, 1968, Fig. 10). Inverted
pigeonites are now accepted as such by most mineralogists, although only one ...

Principles of Igneous and Metamorphic Petrology
orthopyroxene and augite exsolve from one another on planes that very nearly
parallel (100). Pigeonite that cools slowly first develops fine (001) lamellae of
augite. On cooling to the clino- to ortho-inversion temperature (Fig. 10.29(B)), the
...

The Palisades Sill, New Jersey
Pigeonite in the Mg-rich fractionation stages has a complementary relationship to
orthopyroxene of the Palisades type, which is inverted pigeonite. No evidence
has been seen to suggest that pigeonite bears a direct reaction relationship to
the ...
