leucite
Leucite is a technical term used primarily in mineralogy and geology. It is characterized by its specific chemical composition and its occurrence in alkaline volcanic rocks, making it a diagnostic mineral for identifying certain types of magma.
As a mineral name, it functions as a mass noun when referring to the substance in general, though it can be used as a countable noun when referring to individual crystals or specific mineral specimens.
Meanings
Examples
The geologist identified a small crystal of leucite in the volcanic rock sample.
Is this specimen leucite or just a piece of common feldspar?
Leucite typically occurs in potassium rich igneous rocks.
I wonder if this leucite crystal was formed during the initial cooling of the magma.
The thin section of the rock shows several euhedral grains of leucite.
Look at how the leucite reflects light in this sample.
Leucite is a key indicator of an undersaturated alkaline magma.
The mineralogist noted that the leucite had undergone slight alteration over time.
