Abstract
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.
