The geology around Perth is quite different from the eastern states in that there is little variety in the types of rocks exposed. All the same there are some very interesting and special features to observe.
The oldest rocks in the Perth area are exposed in quarries in the Darling Range to the east. [...]
In my discussion of the Perth geological cross-section I concluded that the thick sedimentary deposits filling the Perth Basin likely extended across the Darling Plateau to the east. It seemed to me that these thick and extensive sediments would not have ended abruptly at the Darling Fault but continued, by the Principle of Lateral Continuity, [...]
The figure here shows an interpreted geological cross-section near Perth, Western Australia. It’s taken from the 1:250,000 scale geological map SH-50-14 publised in 1978 by the Geological Survey of Western Australia.
As I have mentioned before, I look at sections like these and interpret them using biblical history.
Section A-B is approximately 80 km long [...]
Thanks to reader JS who sent two images of the windgap near Perth, Western Australia: a closeup of Walyunga NP, and a larger scale image of the Perth coast. They were obtained from Google Earth. JS said:
“The first is a Google Earth screenshot, in which the purple represents a filled-in contour of 80m asl [...]
I’m organizing a geological field trip for the Perth region, Western australia, on 17 March 2012 (find details here). This means lots of research but fortunately there is much excellent geological material available from geological organizations and on the web.
This material, including maps, reports, papers and field guides, is a fantastic resource because the exploration [...]
