Summary[edit]

a. Flowing water carries sediment particles in suspension and these are deposited out on the lee side of the slope, where the velocities are lower.

b. Due to deposition on its lee side, the slope 'moves' forward producing layers' of the form indicated so producing a cross-stratified unit.

c. After the formation of one cross-stratified unit, its top is eroded and another formed above it.

d. Two units of cross-stratification formed without any erosion occurring.

e. Two units of cross-stratification produced by deposition and erosion, so that their tops are truncated. Sedimentary structures: the development of cross bedding in a water flow. Adapted from the Open University Science Foundation Course units 26 and 27 Earth History land 11 (1971, Milton Keynes: The Open University) and Bunyan et al., Building Stones of Edinburgh, 1st edition (1987, Edinburgh: Edinburgh Geological Society).
