Monazite
Monazite is a phosphate mineral that is rich in light rare earth elements (LREE). It is commonly found in various rock types and is used as a reliable geochronometer to date magmatic and metamorphic rocks. Monazite can also be found in hydrothermal mineral deposits and low-grade metasedimentary rocks. From: Earth-Science Reviews, 2024
