A Mossbauer Effect Study of Triplite and Related Minerals
نویسنده
چکیده
Mdssbauer parameters are reported for the phosphate minerals triplite, zwieselite, triploidite, and wolfeite. Analysis of the absorption data confirms the existence of non-equivalent ferrous ions. The broadening of the resonance peaks is rationalized on the basis of a microscopic disorder due to half-occupied fluorine sites in the fluoride minerals and to sets of closelv related metal sites in the hydroxy minerals.

A Mossbauer investigation of iron-rich terrestrial hydrothermal vent systems: lessons for Mars exploration.
Hydrothermal spring systems may well have been present on early Mars and could have served as a habitat for primitive life. The integrated instrument suite of the Athena Rover has, as a component on the robotic arm, a Mossbauer spectrometer. In the context of future Mars exploration we present results of Mossbauer analysis of a suite of samples from an iron-rich thermal spring in the Chocolate ...
متن کاملCrystal Chemistry and Statistical Analysis of Iron
With an emphasis on assessment of reproducibility and precision of results, the technique of Mossbauer spectroscopy is applied to three groups of materials with increasing structural complexity: simple mineral standards, multivalent and multisite ferruginous micas, and multisite silicate glasses. In order to study the underlying accuracy of Mossbauer measurements of minerals, two mineral standa...

Introduction: An enigma of Venusian mineralogy is the suggestion that Fe3+bearing minerals exist under the reducing conditions of the Venusian atmosphere. Analysis of the spectrophotometric data from the Venera 13 and 14 missions, combined with the laboratory reflectance spectral measurements of oxidized basalts at elevatedtemperatures, led to the suggestion that metastable hematite might exist...
متن کاملA Study of Iron in Fired Clay : Mössbauer Effect and Magnetic Measurements
A potters clay from the Gorgan plain, in N. E. Iran, has been fired successively at temperatures up to the melting point 1 200 "C in an atmosphere of air or 5 % CO in moist COz. Mossbauer spectra at 296 K and 4.2 K allow the determination of the relative amounts of iron in well-crystallised haematite or magnetite, of poorly-crystallised and fine-particle ferric oxide or hydroxide, and of iron d...
متن کاملSuperspace description of wagnerite-group minerals (Mg,Fe,Mn)2(PO4)(F,OH)
Reinvestigation of more than 40 samples of minerals belonging to the wagnerite group (Mg, Fe, Mn)2(PO4)(F,OH) from diverse geological environments worldwide, using single-crystal X-ray diffraction analysis, showed that most crystals have incommensurate structures and, as such, are not adequately described with known polytype models (2b), (3b), (5b), (7b) and (9b). Therefore, we present here a u...
