This paper deals with some surface properties of gravels from Patagonia, which have been called 'tehuelches' gravels in the geological literature. These properties are produced by diagenesis of the deposit when in place, but once the pebbles are removed, they change their shape and original features. Measurements of more than one hundred clasts have been made. Differences between original and fragmented clasts are shown in text and illustrations.
