There are many examples of ancient sand bodies which have been interpreted as having a tidal origin. Most of them, however, are intertidal to very shallow subtidal, and represent lagoonal sand flats, tidal channel or estuarine channel and sand flat environments. There are remarkably few well described examples of ancient shelf/shallow marine subtidal sand bodies -- the few examples that exist will be the topic of these notes.

Shelf sandstone reservoirs are becoming a more and more common exploration target. What they are, how they may be characterized, and how they differ from shoreline and deep-water deposits in the subject of this publication. Shelf sands and sandstone reservoirs are among the more poorly understood types of sandstones. Continental, shoreline and deep water sandstones have all been studied in much more depth than have shelf sands and sandstones. However, during the last fifteen years significant progress has been made in understanding shelf sands and sandstones. Studies of modern sediments have allowed us to understand many of the depositional processes active on the shelf. This book is intended to be an up-to-date summary of shelf processes and products. The papers are intended for those new to shelf sands and sandstones as well as the shelf specialist.
