 This is the Oedola mud spell, and as you can see, it has very fine grain texture, and you can see the bedding, which is about 10 degrees and everything like that. So these are the original layers right now in sort of 20, 30, 40 meters of ocean water where the mud settles out very slowly. So if we were to go out there in the ocean right now into this sort of depth of water, we would find only mud settling out. So this has been sorted by energy down from the hills up there, out to sea, and then settling out. And the only thing they can get out there is the mud, because the sands on the beach, the gravels in the estuary, the boulders are up there in the rivers, and so we sorted it mechanically by water to lay down mud. Now this mud is about 290 million years ago, was then buried, lithified, and then subsequently uplifted to find itself sitting on the coast very near the environment that it was originally deposited in, just by coincidence. This could be atop of Himalayas right now. It just happens to be here in Oedola. Now this is part of the Sydney Basin, which is a big triangular space that heads up to Newcastle and goes inland a ways, down to South Burris here, and within this we're seeing a really good view of the Gondwana glaciation. So this glacial event that occurred on all of the Gondwana continents, India, Africa, South America, Australia, back when we were one continent, and this was shedding off, the glaciers were coming off the side.
