Origin of leuciteGerman leucit, now leuzit ( from Classical Greek leukos, white: see light) + -it, -ite
(countable and uncountable, plural leucites)
- (mineralogy) A mineral of silica-poor igneous, plutonic and volcanic rocks. Chemically, leucite is a potassium feldspar with insufficient silica to satisfy the chemical bonds. Because of the unfilled bonds, leucite weathers rapidly and can only be seen as inclusions in freshly broken rock.
- (botany) A leucoplast.
Ancient Greek λευκός (leukos, “white”) + -ite.
