ЧТО ОЗНАЧАЕТ СЛОВО OLIGOCLASE
олигоклаз
Олигоклаз представляет собой породообразующий минерал, принадлежащий плагиоклазным полевым шпатам. В химическом составе и в его кристаллографических и физических характеристиках он является промежуточным между альбитом и анортитом. Албит: молярное отношение анортита колеблется от 90:10 до 70:30. Олигоклаз - полевой шпат высокого натрия, кристаллизующийся в триклинной системе. Твердость по Моосу составляет от 6 до 6,5, а удельный вес 2,64-2,66. Показатели преломления: nα = 1,533-1,543, nβ = 1,537-1,548 и nγ = 1,542-1,552. В цвет он обычно белый, с оттенками серого, зеленого или красного.
