dc.description.abstract | Chladniite, a complex phosphate species belonging to the fillowite group so far only found in meteorites, was identified in a pegmatite from Córdoba (Argentina) as inclusions in beusite. Applying synchrotron through-the-substrate microdiffraction technique (tts-μXRD) to polished thin sections prepared on very thin glass substrates (0.1 mm), diffraction data with nearly single-crystal quality were directly measured at selected chladniite microvolumes of the section. Chladniite is trigonal (space group R-3), with a = 15.0133(3) Å, c = 42.887(2) Å, V = 8371.6(5) Å3. The subsequent crystal structure refinement confirms that the accuracy attainable by using 0.1 mm thick glass-substrates is comparable to that of routine single-crystal measurements [R1=3.34% for 1617 unique reflections]. The refined crystal structure of pegmatitic chladniite differs from meteoritic one in the cation ordering (Mg, Fe+Mn and Ca) at the various metal sites, with Mn being dominant at the M(1) position. | es_ES |
dc.description.sponsorship | Thanks are due to Mr. Luis Gordón and Mr. Marc Puigcerver (Lab. de Preparació de Làmines Primes, Dpt. de Geologia, U. Autònoma de Barcelona) for their decisive contribution in the development of the technique, and to Dr. Jorge Sfragulla (U. Nac. de Córdoba) for help with the field work.
