Industry:Astronomy
Um componente geoquímico em rochas lunares ricas em potássio (K), elementos de terras raras (REE), fósforo (P), histórico e outros elementos incompatíveis. Esses elementos não são incorporados aos minerais formadores de rochas comuns durante a cristalização de magma, portanto, eles se enriquecem no magma residual e nas rochas finalmente formadas a partir dele.
