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

Cenozoic calc-alkaline ignimbrites and related lavas from N.W. Sardinia (Italy), which are closely associated with andesites, have dacitic to rhyolitic composition. The ignimbritic rocks underwent fractional crystallization dominated by plagioclase. The model calculations for REE, Ba, Sr, and Rb are
