Summary: Two occurrences of rutile are reported from Big Bell in Western Australia containing up to 5·8 wt % WO3, 1·7 wt % Sb2O5, and 1·7 wt % FeO. One occurs in a mica schist, and the other in a pegmatite, and both contain a fine intergrowth of ilmenite lamellae. Small grains of gudmundite are associated with the rutile in the pegmatite. Microprobe analyses do not conclusively establish the mechanism of isomorphous substitution.
