plagioclases's Usage Examples:

Andesite shows similar composition to dacite samples, though sodic plagioclases and amphiboles are not as common.

formation may have been the result of the consumption of CaO and SiO2 as plagioclases decomposed into sodalite and nepheline as well as alkali-calcium exchange.

coarse-grained plagioclase minerals, surrounded by a matrix of fine-grained plagioclases and pyroxenes; some iron oxides are also present.

The lunar crust consists primarily of plagioclases formed when aluminium and calcium condensed and combined with silicates.

These phenocrysts are pyroxenes (augite and pigeonite), plagioclases, opaque crystals such as titanium rich magnetite or ilmenite, and occasionally.

basaltic rocks is marked by well-aligned elongated pyroxenes and micro-plagioclases.

with intergrowths of albite and orthoclase or microcline, while the plagioclases are generally antiperthites and intermediate mesoperthites occur too.

Structures that imply tectonic movements are signs of cataclasis: on magmatic plagioclases on groundmass minerals like quartz along the edges of microcline phenocrysts.

The lamellar separation only occurs in plagioclases of a certain composition; those of calcic labradorite and bytownite (anorthite.

"Physicochemical parameters of the crystallization of plagioclases in basaltic rocks from guyots of the Magellan Seamounts (Pacific Ocean)".

Structures that imply tectonic movements are signs of cataclasis: on magmatic plagioclases on groundmass minerals like quartz along the.

Kimura and Ikeda (1995) also suggest that hedenbergite formation may have been the result of the consumption of CaO and SiO2 as plagioclases decomposed into sodalite and nepheline as well as alkali-calcium exchange before the condrules' incorporation into the parent body.
