Re: Chessboard structures: atom-scale imaging of homologues from the kobellite series
Il lavoro è molto interessante.
Verosimilmente a Tavagnasco ci sono le medesime condizioni e siamo di fronte alla formazione di assemblaggi di kobellite e izoklakeite [o meglio - forse - kobellite-tintinaite (serie isotipica) e giessenite-izoklakeite (serie omeotipica)].

Anche se non ancora pubblicato il testo c'è ed è definitivo.
Te lo passo.

Ciao Marco,
anch'io prenoto una copia, tanto per complicarmi un po' la vita!...
Grazie, Vinci

Pubblicazione effettuata.

▪ Li, W., Ciobanu, C.L., Slattery, A., Cook, N.J., Liu, W., Wade, B.P., Xie, G. (2019): Chessboard structures: atom-scale imaging of homologues from the kobellite series. American Mineralogist, 104, 459–462.
Abstract:
High-angle annular dark-field scanning transmission electron microscopy is a powerful Z-contrast technique able to depict the structural motifs in Pb-(Bi-Sb)-sulfosalts. Using two homologs from the kobellite homologous series, a group of “chessboard derivative structures,” represented by Bi-, and Sb-rich pairs of natural phases (the kobellite-tintinaite isotypic series and giessenite-izoklakeite homeotypic series), we visualize the slabs underpinning crystal structural modularity for the N = 2 homolog kobellite and the N = 4 homolog, in this case a Bi-rich izoklakeite [Sb/(Sb+Bi) = 0.35]. The homolog number, N, can be readily calculated as N = n1/6 – 1 and N = n2/4, where n1 and n2 are the numbers of atoms in the PbS- and SnS-motifs, respectively. Atom-scale imaging of thinned foils extracted in situ from samples for which compositional data are available also reveals syntactic unit-cell scale intergrowths on [001] zone axis with akobellite || bizoklakeite. These are as small as half-unit cells of bizoklakeite and one-unit cell akobellite. Replacement relationships are also observed as irregular slabs of kobellite “intruding” into izoklakeite. Both banded and irregular intergrowths account for the compositional fields measured at the micrometer scale.
