This book is both an acknowledgment of Harold Reading's commitment and service to the International Association of Sedimentologists, and a tribute to his pivotal role in the development of facies sedimentology. In a very personal compilation, fifteen of Harold's graduate students, some in association with their graduate students or colleagues, have contributed original papers on a wide variety of topics.

The volume is intentionally eclectic as a means of illustrating the breadth of knowledge and interest that Harold Reading brought to the field of sedimentary facies analysis.

Six papers are concerned with clastic facies analysis in settings that range from alluvial basins through shorelines and tidal seas to turbidite basins. Also included is a discussion of the varied environmental settings of iron formations, and a commentary on the difficulty of applying Walther's Law in a volcanic setting.

Tectonic control on sedimentation is documented in two papers concerned with rift-related alluvial and lacustrine settings: a third illustrates the influence of growth-faulting on preserved stratigraphic successions whereas a fourth illustrates the value of integrating classical facies sedimentology and geochemistry in the analysis of a syn-tectonic melange.

North Sea seismic data provide a basis for the interpretation of enigmatic, very large scale ridge-trough systems, and a new sequence-stratigraphic interpretation is offered for the Millstone Grit of the northern Pennines.
