About this book

The purpose of this monograph is to provide participants in my various short courses with a brief statement of the material I cover in my lectures. In addition, key illustrations are reproduced for guidance. A brief bibliography of reference material is appended to each chapter. The bibliographic material includes those references that I consider critical to my remarks. No claim is made of topical or bibliographic completeness. This monograph also is intended as a brief summary of depositional processes, Holocene sediments, ancient counterparts of depositional environments, and examples of oil- and gas-bearing stratigraphic traps in five depositional environments. This summary is intended to complement lecture and reading courses dealing with sedimentology, depositional systems, sedimentary facies, sedimentary environments, sandstone diagenesis, and sedimentary modelling as a predictive tool for exploration. The student is cautioned, however, that this monograph is merely an introduction and summary overview of the subject. More complete treatments appear in standard textbooks. Sedimentology has changed and advanced over the past twenty-five years, in part because the American oil industry needed to make predictions about the occurrence of the harder-to-find stratigraphic traps. In addition, the development of plate-tectonic theory, and supportive data from the Deep Sea Drilling Project, have caused sedimentology to change from an essentially descriptive science to a mature, predictive science. The 1960s and 1970s in particular witnessed an explosion of new insights and understanding of how sediments are deposited, and how sedimentary rocks are formed.

2. Fluvial Sand Bodies
Abstract
The sediments of fluvial systems have interested geologists for some time. A large body of literature has grown up around the problems of fluvial processes (Leopold et al., 1964; Miall, 1978a), fluvial sediments (Allen, 1965; Miall, 1978a), and fluvial facies models (Miall, 1978a, Reading, 1979). Fluvial sandstone beds are known to contain petroleum reservoirs (Nanz, 1954; Harms, 1966; Berg, 1968; MacKenzie, 1972) and also form host rocks for the well-known sandstone-type uranium deposits found in the Rocky Mountains and the Gulf Coastal Plain (Fischer, 1970, 1974; Galloway, 1977).

3. Beach Barrier Sand Bodies
Abstract
Beach and barrier island sand bodies occur along and are characteristic of wave-dominated coasts of low relief, or coasts which are characterized by sea cliffs of bedrock. The development and preservation of beach and barrier island deposits appear to be related to the relative intensity of wave processes and tidal processes along a coast line. As shown by Davies (1964), and later by Hayes (1975), coasts are classified into three groups according to tidal range (Table 3.1). Beaches and barrier islands tend to be preserved best in, and are characteristic of, microtidal coastlines, and in many instances, also of mesotidal coastlines.

4. Tidal Sand Bodies
Abstract
This section reviews the salient features of sandy tidalites, which are sandy sediments deposited by tidal currents (Klein, 1971). Such sands occur in regions where tidal current systems are dominant. Tidal current systems are known to occur as depositional agents in a variety of water depths ranging from tidal flats at sea level to depths of 2,000 to 2,500 meters (Keller et al., 1973; Shepard et al., 1979; Shepard and Marshall, 1973; Lonsdale et al., 1972; Lonsdale and Malfait, 1974; Shepard et al., 1979). Thus the deposition of sandy tidalites can occur in a variety of coastal settings, including deltas, barrier island complexes (especially tidal inlets), tidal marshes, and tidal deltas. Preservation of tidalites on coastlines is favored in part in mesotidal coasts, and totally in macrotidal coastlines. The dominant coastal setting where such sediments occur is the tidal flats.

5. Deltas
Abstract
The deltaic sand body environment is one of the most complex depositional systems reviewed in this monograph. The complexity of deltas originates directly from the relative interplay of riverine input, wave energy flux, tidal energy flux, sediment dispersal, climate, and tectonic setting, among other variables (Galloway, 1975; Coleman, 1976).

6. Turbidite Sandstone Bodies
Abstract
Turbidite sand bodies comprise part of a broad spectrum of sediments deposited by subaqueous gravity processes in deep-water marine environments. These processes are diverse in type (Figure 6.1), but all constitute part of a continuum. This continuum was classified formally by Middleton and Hampton (1973), who recognized four classes ranging from debris flow to grain flow to fluidized sediment flow to turbidity currents. Figure 6.1 shows a modification of their classification scheme and adds one other end member, namely the large submarine slumps and slides which have been described and recognized from several places (Moore, 1977; Booth, 1979; Doyle et al., 1979; Keller et al., 1979; Schlee et al., 1979). The sediment support mechanism for each of these transport processes is different and permits segregation into distinct classes, as suggested by Middleton and Hampton (1973), although it must be emphasized that the role of internal pore pressure and liquefaction, as well as relative water content, makes it difficult under natural conditions to observe these class distinctions so clearly (Lowe, 1976; Lawson, 1979a). Although this chapter will review the slump processes, as well as the four groups of processes proposed by Middleton and Hampton (1973), which comprise part of one continuum (Figure 6.1), and use the terms they suggested, care must be take in their application because of the total gradational relations that exist between each class.
