Descripción
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 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 the meteoritic one in the cation ordering (Mg, FeþMn and Ca) at the various metal sites, with Mn being dominant at the M(1) position.
