Pyroxene in thin section. Ppl image 10x field of view 2mm hourglass zoning in a pyroxene. Augite 2 thin section hfov 2mm get 360 live interaction. Commonly found as slender prismatic to bladed crystals with a diamon shaped cross section showing the amphibole cleavage at 56 and 124.
Large photo is1 7 mm wide. Image by elizabeth thomas. Pyroxene any of a group of important rock forming silicate minerals of variable composition among which calcium magnesium and iron rich varieties predominate.
Although aluminium substitutes extensively for silicon in silicates consisting of feldspars and amphiboles the substitution occurs only to a confined extent in most pyroxenes. A thin section of green pyroxene. The xenolith is dominated by green peridot olivine together with black orthopyroxene and spinel crystals and rare grass green diopside grains.
Xpl image 10x field of view 2mm hourglass zoning in a pyroxene. Pyroxene is a set of essential rock forming inosilicate minerals discovered in many igneous and metamorphic rocks pyroxenes have the general components is xy si al 2o6. Pyroxenes are the most significant and abundant group of rock forming ferromagnesian silicates.
Sub ophitic texture with clinopyroxene and plagioclase altered to clay xpl. Commonly occurs in eclogites in association with garnet. Longitudinal sections are roughly rectangular and show only one cleavage direction.
Crystals are usually stubby prisms elongate along the c axis. Photomicrograph of orthopyroxene low birefringence skinny lamellae surrounded by clinopyroxene higer birefringence coarse lamellae. They are found in almost every variety.
