Composição química e isótopos de oxigênio em cassiterita e wolframita nos greisens do albita granito Palanqueta, depósito de estanho de Bom Futuro (RO)

Abstract: Resumo O Estado de Rondônia hospeda suítes graníticas meso a neoproterozóicas portadores de Sn, W, Nb, Ta, F e gemas, associadas à greisens, veios, brechas e pegmatitos, cujas informações sobre as composições químicas, isotópicas e de inclusões fluidas dos minerais-minérios ainda são discretas. Esse trabalho apresenta estudo sobre a composição química e isotópica (δ 18 O) de cassiterita e wolframita, encontradas nos greisens do albita granito Palanqueta, o qual faz parte do depósito de estanho do Bom Futuro.
