Abstract
Braunite mineral from Triodi manganese deposits (India) has been studied by Mössbauer spectroscopy. Room temperature Mössbauer spectra show a well resolved quadrupole splitting which is attributed to the substitution of iron in Mn (2) site. Emergence of another doublet at liquid nitrogen temperature has been attributed to the location of small quantities of iron in Mn (4) site. Iron is in Fe III and high spin state. At 4.2 K the internal magnetic field is 415 kOe.
