Abstract

X-ray diffraction Rietveld structure-refinement data for synthetic lepidolite-1M micas in the polylithionite (abbreviated here as Pol) – trilithionite (Tri) – potassium ephesite (K-Eph) join, K(Li2-xAl1+x)(Si4-2xAl2x)O10(OH/OD,F)2 (x = 0.0–1.0), are reported. In the products synthesized with starting materials of the F2Pol100Eph00 (fluoro-Pol) and (OD/OH)Pol0Eph100 (hydroxyl-K-Eph) end members mixtures, up to three coexisting micas are crystallized involving the multisite substitutions, i. e., [6]Li-1[4]Si-1[6]Al[4]Al and F--1(OH/OD)-.
