nepheline en · NOUN
Etymology
From Ancient Greek νεφέλη (nephélē, “cloud”), because crystals become cloudy when exposed to acid, + -ine.
Meanings
- (countable, uncountable) A feldspathoid mineral of silica-poor igneous, plutonic and volcanic rocks. Chemically, nepheline is a plagioclase feldspar with insufficient silica to satisfy the chemical bonds. Because of the unfilled bonds, nepheline weathers rapidly and can only be seen as inclusions in freshly broken rock.
