The use of a basic total reflection x-ray fluorescence (TXRF) unit coupled to a fine structure MO x-ray tube for the determination of rare earth elements (REEs) in geological materials was investigated. Three certified reference rock materials, viz. shale Awl-l, psammite PRI-1 and schist SBO-1, were

A suite of basanitoids and alkali olivine basalts from Grenada, Lesser Antilles were analyzed for rare earth elements. The REE concentrations of these rocks are characterized by a small variation in the heavy REE (7 to 9 times chondrite) and a large variation in the light REE (17 to 93 times chondri
## Abstract A simple, rapid microcolumn preconcentration and separation technique is described for the determination of the trace rare earth elements Sm, Tm, Ho, and Nd in geological samples by Inductively Coupled Plasma Atomic Emission Spectrometry (ICPβAES). The technique was based on adsorption
