This is consistent with the fact that olivine is typically entrapped in pyroxene and amphibole crystals. |
The highest core recovery occurs in the massive olivine gabbro, which contain lower densities of fractures and are generally undeformed. |
This flow consists of about 30 percent plagioclase, clinopyroxene, and olivine, as small phenocrysts. |
Major mineral phases include plagioclase and pyroxene, with small amounts of opaque minerals, olivine, apatite, and sometimes biotite. |
The magmatic evolution is dominated by low-pressure crystal fractionation of olivine, Cr-spinel, plagioclase and clinopyroxene. |
The groundmass consists mainly of bytownite with large grains of diopside and of colourless olivine, and small octahedrons of magnetite. |
