andesine's Usage Examples:

breccia that has a porphyritic appearance, consisting of plagioclase (andesine) and pyroxene (pigeonite and augite) phenocrysts that are up to 5 mm in.

Composition Intermediate Major minerals: plagioclase (often andesine) and pyroxene or hornblende Accessory minerals: magnetites, biotite, sphene, quartz.

The plagioclase is usually sodium-rich (oligoclase or andesine).

alleged that since 2003, the shopping network has sold a gemstone called andesine-labradorite, without disclosing its treatment, while promising buyers that.

albite (0 to 10) NaAlSi 3O 8 oligoclase (10 to 30) (Na,Ca)(Al,Si)AlSi 2O 8 andesine (30 to 50) NaAlSi 3O 8 – CaAl 2Si 2O 8 labradorite (50 to 70) (Ca,Na)Al(Al.

The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase.

are between rhyodacite and tholeiitic basalt in composition and contain andesine, hypersthene and augite, with a silica (SiO2) content greater than 60%.

intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene.

Feldspar is present as plagioclase (typically oligoclase or andesine) with 10% or less alkali feldspar.

silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene.

composed principally of the silicate minerals plagioclase feldspar (typically andesine), biotite, hornblende, and/or pyroxene.

widely in sodium content, from anorthite to oligoclase, but is typically andesine.

The plagioclase in monzonite is sodium-rich, ranging from oligoclase to andesine, and is moderately well shaped (subhedral to euhedral).
