Oligoclase is a rock-forming mineral belonging to the plagioclase feldspars. In chemical composition and in its crystallographic and physical characters it is intermediate between albite (NaAlSi3O8) and anorthite (CaAl2Si2O8). The albite:anorthite molar ratio of oligoclase ranges from 90:10 to 70:30. Oligoclase is a high sodium feldspar crystallizing in the triclinic system. The Mo

Oligoclase is a common mineral in the more silica-rich varieties of igneous rock and in many metamorphic rocks. Name and discovery [ edit ] The name oligoclase was given by August Breithaupt in 1826 from the Ancient Greek : όλίγος,romanized : oligos,little, and Ancient Greek : κλᾶν,romanized : klân,to break, because the mineral was thought to

Oligoclase, a rock-forming mineral is a member of the plagioclase feldspars. It has intermediate characteristics between an albite and anorthite. The mineral was named by August Breithaupt in 1826 after the Greek words ‘oligos’ and ‘clasein’ which mean little and to break, respectively.
Chemical Formula. (Na,Ca)Al1-2Si3-2O8. Composition. Sodium calcium aluminum silicate. The ratio of sodium to calcium is about 9:1. The amount of aluminum atoms are between 1 and 2, and the amount of silicon atoms are between 3 and 2. In the Plagioclase Feldspar series, Oligoclase contains between 70 and 90 percent Albite (Ab), and between 10
