1. DEVELOPMENT OF A METHODOLOGY FOR CORALS AND SPELEOTHEMS DATING USING THE 230-TH/234-U METHOD, THROUGH CHROMATOGRAPHIC SEPARATION AND QUANTIFICATION BY ALPHA SPECTROMETRY AND FIA-ICP-MS / DESENVOLVIMENTO DE UMA METODOLOGIA PARA DATAÇÃO DE CORAIS E ESPELEOTEMAS UTILIZANDO O MÉTODO DA RAZÃO 230TH/234U, POR SEPARAÇÃO CROMATOGRÁFICA EQUANTIFICAÇÃO POR ESPECTROMETRIA ALFA E FIA-ICP-MS
This paper discusses the age determination of speleothems and corals using Uranium-series- imbalance method, more specifically the daughter deficient method - DD, particularly the 230Th/234U method. Different methodologies were tested using chromatographic extraction separation and quantification by alpha spectrometry and ICP-MS. Three different procedures w
