The Same Pits Twice

Recurrence of Iron Oxyhydroxide Nucleation Sites on Stripped Quartz Grains from a Single Soil Profile

A paper from the School of Underlying Conditions strips the iron coatings from 56 quartz sand grains taken from one subsoil, maps 1,742 etch pits on them, and wets each grain five times to see where the first particles of a new coating form. About two thirds of the pits occupied at one wetting were occupied again at the next, 148 were occupied every time and more than half never were; pit depth and width explain part of the recurrence, and a doubled stripping treatment does not reduce it.
