ABSTRACT      In the Jasimampa LREE (Nb) prospect of Santiago del Estero province, REE- fluorcarbonates, cheralite and strontianite were found in samples of strong fenitized marble, and taienolite occurs in moderate fenitized granite, close to an aegirine vein. Their textures and some chemical compositions are presented and compared to literature data, as well as some genetic considerations are discussed.
