Gold morphology and composition at Panglo, Eastern Goldfields,
Scott, K.M. and Davis, J.J.
Coarse >80 µm gold from the mineralised horizon in the
weathered zone at 30 to 40 m below the surface at Panglo may be
xenomorphic or euhedral. Xenomorphic forms are composed of pseudohexagonal
platelets which are often severely pitted and may also have ?cryptocrystalline
spherules within pits and voids. Euhedral gold occurs as aggregates
or as single dodecahedral or elongate crystals. No Ag was detected
in any of the grains studied. All the above features are consistent
with the gold being supergene, possibly forming during lateritization
and being corroded during the subsequent arid period.
