Mossbauer Spectra of Soil Kaolins from South-Western Australia
Iron Kaolin Mossbauer spectroscopy
2011/12/31
Six well-characterized soil kaolins from widely separated sites in south-western Australia and four reference kaolins were studied by 57Fe M鰏sbauer spectroscopy at room temperature after removal of no...
Interpretation of Mossbauer Spectra of Nontronite, Celadonite, and Glauconite
Atomic coordinates Celadonite Electric field gradient Glauconite Mossbauer spectroscopy Nontronite
2012/1/11
A new approach to the interpretation of Mössbauer spectra of Fe3+-phyllosilicates having vacant trans-octahedra is based on (1) crystal structure simulation methods that allow for the size and th...
Iron Sites in Nontronite and the Effect of Interlayer Cations From Mossbauer Spectra
Interlayer cation Iron Mossbauer spectroscopy Nontronite Octahedral site
2011/11/25
Abstract: The 57Fe Mössbauer spectra of untreated, Ca- and K-saturated nontronite from Garfield, Washington, were measured. The spectrum of the untreated sample was computer-fitted to 8 peaks def...

A sample of ferripyrophyllite, a mineral with ideal composition Fe2Si4O10(OH)2, was analyzed by Mössbauer spectroscopy, magnetization and magnetic susceptibility measurements. The iron is entirel...
Mossbauer spectra of 15 smectites were investigated. In these samples, ferric iron occupies both M(1) and M(2) octahedral sites, the distribution being partly determined by the relative covalency of t...
