About This Publication (from its 1969 publication announcement)
This classic publication is a syllabus published in conjunction with a Research Colloquium of the Bureau of Economic Geology, August 27-29,1969. It includes discussion notes, 168 maps and other text figures, and a list of 321 selected references pertaining to modern and ancient delta systems. The discussion notes are:

Delta Systems and Deltaic Deposition, by A. J. Scott and W. L. Fisher. Includes concepts of depositional systems; examination of principal depositional environments, processes, and specific facies of a spectrum of Holocene delta systems; stratigraphic classification of modern and ancient delta systems; considerations of basic kinds and patterns of delta facies and delta systems recognizable in ancient basin fills.

Gulf Coast Basin Tertiary Delta Systems, by W. L. Fisher. A consideration of ancient delta systems in the Lower Wilcox, Upper Wilcox, Yegua, and other units of the northwestern Gulf Coast Basin. Emphasis is placed on basic kinds of delta systems, constituent facies and bases for recognition, sand patterns and trends, lateral and vertical facies trends, E-log characteristics in facies recognition and evaluation, and structural association.

North Texas (Eastern Shelf) Pennsylvanian Delta Systems, by L. F. Brown, Jr. Includes consideration of ancient delta systems in the Cisco Group of North-Central Texas Eastern Shelf with emphasis on facies patterns, channel sand distribution, relationship of shelf carbonates and slope and basinal systems to delta systems; compactional features of sand-shale sequences; a depositional model for the Eastern Shelf; and role of deltas in cyclothemic deposition.

Delta Systems and Oil and Gas Occurrence, by W. L. Fisher and L. F. Brown, Jr. Includes discussion of Gulf Coast Basin Lower Wilcox, Upper Wilcox, Yegua, and Jackson trends and Eastern Shelf Cisco trends with a consideration of oil and gas trends in ancient delta systems of these trends; the origin, migration, and entrapment of hydrocarbons in delta sediments; relationship of specific delta facies to regional and local structures; geometry of delta reservoirs; porosity and permeability of delta reservoirs; and use of a delta model in predicting reservoir conditions.

Delta Systems in Other Basins, by L. F. Brown, Jr., and W. L. Fisher. A consideration of delta systems in other oil and gas basins of North America including examples from Cretaceous of U. S. Western Interior and Alaska North Slope basins and Upper Paleozoic of U. S. Eastern Interior and Midcontinent basins.
