[QUOTE="Hawkear, post: 641798, member: 4728"] Hi aussiefarmer. I would say just knocked and rounded by tumbling action in river gravels. Gold is very malleable and can be rounded very easily. Gold is heavy and difficult to move so lighter yet harder material will move at a different rate causing abrasion action between the two with the softer gold being rounded more. Quartz is a lot harder than gold yet even it can be rounded after eons of abrasion. Here is a pic of quartz gravel that has been rounded by tumbling in a river or possibly even a shoreline by wave action. Any gold in that gravel should be very smoothed and it is. The picture is of the subbasaltic gravels at Happy Valley. [ATTACH type="full" alt="571F83AA-3DEB-47B7-9CB6-6696EE4E2432.jpeg"]1076[/ATTACH] [/QUOTE]
