Mooreite is a mineral belonging to the rare earth carbonate mineral group. It is identified as a specific combination of elements within this group, consisting of the chemical composition (REE,Ca,Fe)(CO3)OH·H2O. The mineral is named after its discoverer, geologist and mineralogist, Chester Moore Jr.
Mooreite occurs as transparent to translucent white or pale yellow crystals, commonly exhibiting a vitreous to greasy luster. It often forms in granular or prismatic aggregates, which are frequently found associated with other rare earth minerals. This mineral can be found in a few select locations worldwide, but its occurrence is considered relatively uncommon.
In terms of physical properties, mooreite typically has a Mohs hardness ranging from 3 to 4, indicating moderate hardness. It crystallizes in the orthorhombic crystal system, and its crystals tend to have prismatic or tabular habits. Mooreite also exhibits a distinct cleavage along two directions.
Due to its rare occurrence and limited distribution, mooreite is primarily of interest to mineral collectors and researchers studying rare earth minerals. These minerals have various industrial applications, specifically in the production of magnets, catalysts, and electronics.
In summary, mooreite is a rare earth carbonate mineral with a specific chemical composition that forms transparent to translucent white or pale yellow crystals. It is named after the geologist Chester Moore Jr. and is mainly valued by collectors and researchers in the field of rare earth minerals.
