Hi all, I am wondering if any members have some good local knowledge on the geology in an around the Talbot, Amherst areas in Victoria. I am investigating different sites to do a doze & detect (buying the land @ doze n detect licence).
The surface is amazing looking ground, but when we dig down we find the decomposed stained quartz material is only about 400 mm deep. Below that is 3m plus of either red or white pipe clay with almost no rock. Sometimes we strike a small band of decomposed reef material below thus. The areas we are in are covered with old workings. We have not hit bedrock.
I am confused about why the surface material of decomposed reef would only be very shallow. Also, if the small bands of quartz material we strike at 3m depth are wash material, then it has not travelled far as it is all very jagged, no pebbles, just like the surface. When we look at the vast tailings piles there is a vast amount of quartz in it. Where they got this from I don't know.
Is the deep layer actually a wash, or decomposed reef just layered? Maybe the old boys were digging further than us and struck a wider band of pay material?
If anyone has LOCAL knowledge I'd really appreciate a comment.
