Lloyd, I think I disagree, or, more correctly, would like to discuss further your and my ideas about how sand is created.
From what i see i don't think most sand is formed by rock erosion. Norfolk, England is a chalky area yet has a variety of sand colour and texture. Malta is a limestone island but its sand varies in colour and texture in the few areas you can find it. Why do you find any sand On Malta and Gozo?
The Sahara seems to large an area to be beach sand and also has a lot of non salty water (fossil water) in and underneath it. It does not seem to make much sense to me for it to have been a beach or ocean when it occupies most of north africa.
I suspect that sand is some sort of creation of the EU, similar to Dusty Plasma and the fact that
minerals/dust are found being formed by a Plasma Discharge, from what the Scientits call a quasar or a Black Hole.
Sand appears in unlikely spots, in the middle of mountain ranges for example and in isolated spots. You have the sands covering Egypts temples, the Sahara advancing and even the great
Sand Floods of Norfolk
Of course I am not saying that all sand is not produced by wave erosion but I do not think it is much. Along the great beaches of Australia the rock is not white and in certain areas you do not find exposed rock near the beaches. Also in Norfolk (England) you have very large sand dunes along the shores yet no rock.
Does the formation of Dust and minerals in space also explain where the Earths dust/soil comes from? Is it also an EU affect along the lines of dust and sand? Would this help explain why buildings are constantly being covered over by soil at a great rate. Is it an EU event, maybe the the result of a discharge or exchange?
If it is created in this manner could it explain sudden layers in the earth, not due to some disaster but created/exchanged by the Earth in response to a change in the EU?
P.S. I had never thought about how much sand is in sandstone, so I will have to investigate that one further, or, can you give some more examples of what you have found about it and the data?
