The storm and tidal currents that sweep the surfaces of continental shelves imprint a variety of morphologic and textural patterns on these surfaces. As the surfaces aggrade, the grain size gradients and bedform arrays become the textures, structures and stratification patterns of the resulting sedimentary sequences. This paper describes textural gradients and bedform arrays characteristic of shelf surfaces, and the process of strata formation.

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.
