Nodules and crystals of olivine-spinel-pyroxene, pyroxene, and amphibole are associated with the feldspar crystals in undifferentiated lava.The structural state of the alkali feldspar crystals is high, whereas that of the plagioclase appears to range from high to low. The feldspar inclusions probably formed in a deep-seated high-temperature environment. This content is PDF only. Please click on the PDF icon to access.
