[QUOTE="Lefty, post: 288333, member: 2976"] Cheers for that Goldirocks - some great info there! Had things been different when I was leaving high school, I might well have made geology a serious undertaking. I have a mate who has a geology degree but has never worked in the field - he walked out of uni into a previous mining bust before this one and no one was looking for geologists so he had to change tack and by the time things picked up again in that area he was already committed to something else. Are you and your mates on gas exploration? Did you look at the pictures I posted of the wood in the other thread? What are your thoughts? I didn't think we were likely to see the formation of banded agate with quartz crystal centres in the middle of a piece of pet wood [i]without[/i] related thermal activity. Perhaps the wood was already fossilized and the hollows and cracks were later filled by hot silica-saturated water at the time of the eruptions. Is there such a thing as "cold" agate formation? Yes, this is the region the material in the photograph originates from. The other material I mentioned comes from localities some distance (hundreds of kms) to the south and west of that map.
