Abstract

A morphological study of zircons from the granitic rocks of southeastern South Australia has been made using reduced major axes, length/breadth ratios, colour, zoning and other features. In general, zircons in the biotite adamellites (Encounter Bay and Kingston areas) are more elongate, less euhedral and freer of inclusions and zoning than those occurring in the other granitic rocks of the region. Results suggest that the biotite adamellites are genetically related (they share the same zircon characteristics) and that they are unrelated to the more widespread eastern zone of hornblende-biotite granite, quartz porphyry and hornblende and biotite microgranite. The rocks in the eastern zone share very similar zircons and appear to be related.
