monazite
Sign in to saveMonazite is a primarily reddish-brown phosphate mineral that contains rare-earth elements. Due to variability in composition, monazite is considered a group of minerals. The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group.

Monazite is a primarily reddish-brown phosphate mineral that contains rare-earth elements. Due to variability in composition, monazite is considered a group of minerals. The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group.
==Types== There are five different most common species of monazite, depending on the relative amounts of the rare-earth elements in the mineral: monazite-(Ce), (the most common member) monazite-(La), monazite-(Nd), monazite-(Sm), monazite-(Gd),
