[QUOTE="Lefty, post: 116524, member: 2976"] Not too sure Silver - doesn't seem to have cleavage, I think most of it is just badly cracked. But definately, there will be some decent un-cracked bits somewhere. Could well be metamorphic I guess, the area it came from is dotted with old volcanic plugs. Mount Hay - once a well-known source of thundereggs, not so many big ones left there these days apparently - is a relatively short distance away. I used to go there looking for carnelian and it only recently struck me just how much stuff is lying there in the gravel that I had been missing because I was fixated on one thing. It is a mass of petrified wood and agatey-type materials, who knows what else I've just been walking over? Actually, the area is about the closest point to the coast that is identified as being potentially precious opal bearing. Not that I've ever found any. But I have a bit of stuff from there that I'm pretty certain is fossilized coral. [/QUOTE]
