leucite

Meaning

Noun

• 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.
• A leucoplast.

Origin

• From Ancient Greek λευκός -ite.
