Rare Earth Elements in the Geological Sciences SpringerLink

Rare earth elements (REE) are an integral part of modern geochemical and petrological studies. The rare earths are widely used, either alone as a group or in combination with other trace elements, to study igneous rock systems and, to a lesser extent, sedimentary and metamorphic rocks. Most of the major advances have been in the field of ...

2021-11-3  The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's
