Zusammenfassung: <jats:title>Summary</jats:title><jats:p>Garnet containing up to 26% SnO<jats:sub>2</jats:sub>, and pyroxene and spinel containing 12% and 10% SnO<jats:sub>2</jats:sub> respectively, occur in a tin-refining slag in association with cassiterite. These tin contents probably represent minimum values for the limit of ionic replacement of Sn<jats:sup>4+</jats:sup> in the structure of these minerals. The absence of tin from coexisting melilite suggests that Sn<jats:sup>4+</jats:sup> is only able to substitute for ions in octahedral co-ordination.</jats:p>
