Crystal structure and doping in synthetic enstatite: an analysis of Li/Fe <sup>3+</sup> -doped single-crystal samples Open
A series of Li + /Fe 3+ -doped enstatite crystals of composition Mg (2–2 x ) Li x Fe x Si 2 O 6 were synthesized and structurally characterized. Under the selected experimental conditions, we grew three crystals of Pbca orthopyroxene (OPX:…

Crystal chemistry of K-tourmalines from the Kumdy-Kol microdiamond deposit, Kokchetav Massif, Kazakhstan Open
Selected crystals of natural K-bearing tourmalines, extracted from a quartzofeldspathic rock from the Kumdy-Kol microdiamond deposit (an ultrahigh-pressure region of Kokchetav Massif, northern Kazakhstan), were characterized using a scanni…

In-situ high-temperature behaviour and breakdown conditions of uvite at room pressure Open
The thermal behaviour of an uvite from San Piero in Campo (Elba Island, Italy) was investigated at room pressure through in-situ High-Temperature X-Ray Powder Diffraction (H T -XRPD), until the breakdown conditions were reached. The variat…

Recommended X-ray single-crystal structure refinement and Rietveld refinement procedure for tremolite Open
A detailed description of the structure of the amphibole-supergroup minerals is very challenging owing to their complex chemical composition that renders the process of cation partition extremely difficult, particularly because of the occu…

Mn-bearing purplish-red tourmaline from the Anjanabonoina pegmatite, Madagascar Open
A gem-quality purplish-red tourmaline sample of alleged liddicoatitic composition from the Anjanabonoina pegmatite, Madagascar, has been fully characterised using a multi-analytical approach to define its crystal-chemical identity. Single-…
