Shannon Shelf-Ridge Sandstones Field Trip
This day in the field is designed to allow you to observe the various facies which occur in one of the many varieties of shelf sandstones. The Shannon Sandstone outcrops of Campanian age (Fig. 1) in the Salt Creek area contain two stacked shelf sand ridges.
The four or five stops to be included on the trip have a somewhat similar coarsening-up sequence at each location. The locations of the stops are shown in Figure 2. Several of the stops have extensive Central Ridge Facies while the others contain, predominently High- and Low-Energy Ridge- Margin Facies as their highest energy facies.

Shelf Sands and Sandstone Reservoirs
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.
