Recent Developments in Fluvial Sedimentology
This volume brings together 36 of the manuscripts that were presented at the Third International Fluvial Sedimentology Conference hosted by Colorado State University in August, 1985. Fluvial systems and sedimentary rock sequences discussed range in age from Holocene to Precambrian and include many diverse areas. The principal objective of the volume was to document the recent developments in the application of facies analysis to the reconstruction of the architecture of fluvial systems. Reconstruction of architecture is an integral part of the overall process of basin analysis.

The Pliocene-Early Pleistocene White Channel gravels in the Klondike area are divided into nine facies, interpreted as proximal braided to distal braidplain sequences and colluvial sediment-gravity flow deposits within a confined valley setting. Results of Markov chain analysis show that the White Channel deposit shows only three well defined trends. These consist of: (1) disorganized gravel overlain by massive to crudely stratified gravel, which passes back into disorganized gravel. These facies are both poorly sorted and represent high flow, tractional bedload and/or mass flow deposition; (2) scoop-shaped crossbedded cobble-gravel overlain by trough crossbedded pebbly sand and gravel.
