Olivine is found as relict cores surrounded by serpentine, and bronzite relics in the serpentine may be partially to completely altered to bastite.
Orthopyroxene (>1.5 mm) occurs as sparse phenocrysts, displaying a hypherstene and bronzite composition ([En.sub.73-87][Fs.sub.11-24][Wo.sub.2-6]; Fig.
Additionally, limited exchange of xenocrysts (labradorite, edenitic amphibole, and bronzite in dacites, oligoclase and andesine in andesitic enclaves) might have occurred during this entrainment stage.

There, the gabbros, mostly norite, occasionally troctolite are generally coarse-grained, equigranular to gently pegmatitic, show a texture from cumulate to holocrystalline and are composed by labradorite, augite and subordinate bronzite, with minor amounts of magnetite, ilmenite, and alteration products.

Petrographically, the basalts are described as containing calcic plagioclase, augite, and rarer pigeonite and bronzite, and Fe-Ti oxides, and vary from holocrystalline to variably vitrophyric ([less than or equal to]30%).
(1) The basalts are dominated by calcic plagioclase ([An.sub.50-70), augitic pyroxene ([En.sub.40-50][Wo.sub.30-40][Fs.sub.15-40]), rare bronzite, and rare equant Fe-Ti oxides as an early liquidus phase.
