Rare earth elements (REE) are widely used in high technologies, medical devices, and especially clean energy. Distribution and origin of REE deposits have become strategic priorities of Mongolia. In order to make clear distribution characteristics and metallogenic features of REE mineralization in Mongolia, we studied more than 80 localities and analyzed more than 250 samples for major, trace and REE. We understood that REE mineralization is strongly controlled by magma types and its distribution shows spatial relation with geodynamic setting.
