[QUOTE="user 4386, post: 647923, member: 4386"] I think even granite experts would have trouble telling if a granite orignated in Tasmania or not - glacial action can do that but I have never seen an example. We did not get very big glaciers in the last glacial periods - it moved further in an earlier ice age (Permian). You will see giant granite boulders north of Queenstown (TAS) and around Heathcote (VIC) where there is no granite bedrock - because of glacial action. But the furthest distance I have found to source in that case is tens of km. Also around Bacchus Marsh. [/QUOTE]
