Rock art #3

Back to Wimbie Beach today and a return, also, to my (uneducated) fascination with the geology around Batemans Bay. This is the best example I've come across so far of a vein of quartz running through the shoreline shelf.

For those interested, let me quote from a Shire Council paper on the natural history of the area:

"Complex events over millions of years resulted in the uplift of the deepest near- continental sea beds to become the highest mountain ranges now present in Australia.

"These former sea beds are the basis of the Greater Batemans Bay geology and date from the Early Ordovician Era, 500 million years ago. They are composed of mudstones, fine-grained sandstones and shales that have been layered, folded and, in some cases, metamorphosed by relatively recent volcanic activity."

Now we know.
