Udden-Wentworth scale
(Science: plant biology) A geometric scale of grain sizes which classifies particles of siliciclastic sediment from 4096 millimetres (boulders) in size down to 0.00006 millimetres (clay).
This scale is almost universally accepted by modern sedimentologists (a type of geologist). It was first proposed in 1898 by Udden and then modified and extended in 1922 by Wentworth.
