This excursion looks at the beginnings of the Adelaide Super Basin, or what was called the Adelaide Geosyncline. At Aldgate the basement rock (Barossa Complex) outcrops as an Inlier. The first basin sediments laid down was the Aldgate Sandstone, we will get a good look at this and explore the basement rocks nearby. Then we go to Emerald Quarry where we will explore surrounding geological features on the edge of the Kanmantoo Basin, the last group of the Adelaide Basin sediments to be laid down and beginnings of Eastern Australia.
We have yet to find in Australia one geologically mapped fault that has earthquakes occurring along it. When it comes to earthquake hazard, most engineers and regulators like smoothed maps without sharp changes, but seismologists like their favourite bullseye. However there is a model of earthquake occurrence that is just in the development stage in Western Australia that looks more like chicken pox. Will it turn out to be useful?
