Abstract
Rudaceous deposits are the coarsest members of a continuous spectrum of clastic or fragmental deposits composed of detrital material which has been transported mechanically. Figure 4.1 defines the position of rudaceous deposits (gravels, conglomerates, breccias) in that spectrum in terms of grain size. When the fragments are approximately of uniform size the deposits are said to be well sorted and when very variable in size, poorly sorted. In the poorly sorted state, suitable qualifiers are used in naming the sediment, such as sandy gravel, pebbly sand or silty clay.
