Geology, Palaeontology & Archaeology / transformng windblown sand into sandstone
« on: 05/04/2013 16:09:12 »
How much sediment is required to overlay loose windblown sand to turn it into sandstone? I have been told repeatedly that the sand in the NC sandhills was covered by sediments that then eroded away leaving no trace of the overlying rock whatsoever. Every case where I have seen windblown sand covered with sediments it was sandstone. Almost always there is very little overburden covering the sandstone.
So how much does it take?
