Data Publication: Boron isotopic and mineral chemical composition in greisen-related Li-Fe micas at the Sadisdorf Li-Sn-(W-Cu) prospect, Erzgebirge, Germany: Pathways and mechanisms for hydrothermal lithium enrichment

The dataset is composed of sample locations descriptions (Table S1), major (Table S2) and trace element (Table S3) compositions of micas, whole-rock (Table S4) and in-situ (Table S5) B isotopic analyses of micas and major lithologies from the Sadisdorf prospect.

In addition it contains calculated relative activities of elements in hydrothermal micas from the Sadisdorf prospect as well as a compitlation of compositionas of magmatic and hydrothermal micas associated to Li-Sn-W-Mo-Nb-Ta deposits worlwide (Table S7).
