We compare two different approaches to fitting the Fe-57 M6ssbauer spectra of paramagnetic state minerals: the widespread practice of using Lorentzian line doublets with adjustable F widths and a new method (Rancourt and Ping, 1991) based on quadrupole splitting distributions (QSDs). We argue that t

We demonstrate by trade-off and error analysis of representative spectra that paramagnetic state M6ssbauer spectroscopy of 2:1 layer silicates cannot resolve the octahedral Fe 2+ cis (M2) and trans (M1) sites. We show that it is impossible to extract cis/trans population ratios from two Fe 2+ double

We develop the methodology of quadrupole splitting distribution (QSD) analysis by evaluating the influences of absorber thickness, absorber texture, and the asumed Lorentzian width on the extracted QSD. We then present the first study to describe the M6ssbauer spectra of members of a mineral family

M6ssbauer spectroscopy has been used to analyse FeS2 thin films obtained by sulphidation of 57Fe evaporated layers. Complementary characterization of the films has been carried out by X-ray diffraction and optical absorption measurements. It is concluded that the two processes (formation and crystal
