Not sure if you have seen this but I know it will interest you both.
I was looking for comparative geology and came across it.
Again, nice in soil gold values at shallow depths.
mc ~100m
I would like to know more about the development of high in soils and, if and why they can go to great depths.
Sorry for my ignorance.
Enjoy and kind regards, Wack.
