[QUOTE="Lefty, post: 410799, member: 2976"] Gday Schultzy. Goldirocks is a geologist and would be best placed to answer your question in the mineral identification thread. However, to me it does fairly closely resemble something called spherelitic rhyolite (spelling?) which is also referred to as "rainforest Jasper" and is found here in my neck of the woods in central QLD at a place called Mount Hay, which also produces thunder eggs. I think it's a particular kind of high-silica lava which has many little agate/chalcedony nodules embedded through it. I can't post links from this device but if you google Mount Hay gemstone tourist park you should see some nice photos of the stuff. They get big slabs of it there that I've seen made into very nice looking coffee table tops. Cheers [/QUOTE]
