Samples of dumortierite from various localities of Brazil (Serra do Espinhaço-Minas Gerais, Macaúbas-Bahia) were analyzed with microprobe and the results were compared with those obtained from samples from Louvincourt dumortierite deposit (Quebec, Canada), Lincoln Hill-Champion Mines dumortierite deposit (Nevada, USA) Jack Creek dumortierite deposits (Montana), Acuélos (Chile) and from Madagascar (locality unknown). Infra-red spectroscopy (FTIR), ERP, Mössbauer effect spectroscopy (MS) were performed on the samples. Fourier transform infrared spectroscopy (FTIR), electron paramagnetic resonance (EPR) and Mössbauer spectroscopy have been used to study dumortierite samples of Brazil and of other origins. FTIR spectroscopy shows the existence of various environments for the OH- groups, which are related to substitutions and/or vacancies in the M1 octahedral site. Mössbauer spectroscopy consistently reveals the presence of divalent iron in 2 different octahedral sites, trivalent iron in one octahedral site and minor IVCT or IMMT iron. EPR also shows that isolated Fe3+ is present in various types of sites. The other signals ascribed to paramagnetic Fe3+ correspond to tetrahedral or more distorted octahedral sites.
