Leucite - Wikipedia
Leucite (from the Greek word leukos meaning white) is a rock -forming mineral of the feldspathoid group, silica-undersaturated and composed of potassium and aluminium tectosilicate KAlSi 2 O 6. [4]
Leucite | Physical - Optical Properties, Uses, Occurrence & More...
Apr 23, 2023 — Leucite is a rather rare mineral, occurring only in igneous rocks, usually in the recent lavas; rarely observed in deepseated rocks. Found in rocks in which the amount of silica in the magma was insufficient to combine with the potassium to form feldspar.
Leucite: The mineral leucite information and pictures
Leucite is a member of the feldspathoid group, forming directly from cooling lava in volcanic rock. It forms in low- silica environments where little Quartz is present. When Leucite forms at high temperatures, it crystallizes as isometric crystals in trapezohedral crystal form.

Leucitite - Wikipedia
Leucitite or leucite rock is an igneous rock containing leucite. It is scarce, many countries such as England being entirely without them. However, they are of wide distribution, occurring in every quarter of the globe.
