Apatite has recently gained considerable attention as a mineral with many uses within the Earth and planetary sciences. Apatite chemistry has recently given new insight into a wide range of geological processes and tools, such as magmatism, metasomatism, planetary geochemistry, and geochronology. In a new article, researchers expand the utility of apatite by presenting a novel way to fingerprint magma chemistry and petrogenesis using apatite inclusions within robust titanite and zircon.
