Sedimentologia y Estratigrafia Today, sediments are largely studied by remote sensing, in one form or another, by adept mousemasters skilled in office survival. Satellite photos, multidimensional seismic surveys, and borehole imagery enable sedimentary rocks to be studied in an airconditioned office without ever actually being looked at. To correctly interpret and understand remotely sensed sediments, however, it is essential to understand the fundamentals of sedimentology, preferably by having studied sediments in the wild.
Modern earth science graduates are familiar with the latest theological debate pertaining to sequence stratigraphy, and the latest computer program for basin modeling, but are often unable to tell granite from arkose or to explain the formation of crossbedding. Worthy attempts by teachers to lead students to the margin of the subject before absorbing its foundations exact a high price. On my last field trip I used the guidebook of the local petroleum exploration society. I visited an outcrop of what the guide described as a carbonatite plug.
This proved to be a raised sea stack of white skeletal limestone. At another locality shales were described as containing horizons of volcanic bombs. These were actually rusty, round fossiliferous siderite concretions. Applied Sedimentology is therefore unashamedly about sensual sedimentology. Applied Sedimentology is divided into three parts: Rock to Sediment, Sediment Sedimented, and Sediment to Rock, reflecting the holistic nature of the sedimentary cycle.
Part I, Rock to Sediment, consists of two chapters. Chapter 2 outlines weathering, showing not only how weathering gives rise to the terrigenous sediments, but also how it mobilizes and concentrates diverse residual ore deposits. Chapter 3, Particles, Pores, and Permeability, describes the texture of sedi- ments and shows how these are related to porosity and permeability. Chapters 4 and 5 describe sedimentary processes and sedimentary structures, respectively.
Chapter 6 outlines the major depositional systems and discusses how their products may serve as petroleum reservoirs and hosts for ore bodies. Chapter 7 describes the subsurface environment within which sediment is turned into rock. Chapter 8 describes clays, sands, and gravels and details their diagenesis and porosity evolution. Chapter 9 does the same for the chemical rocks, describing the mineralogy, composition, and diagenesis of carbonates, evaporites, sedimentary ironstones, coal, phosphates, and chert.
The book concludes with a chapter on sedimentary basins. This describes the mechanics of basin formation, the various types and their sedimentary fill, and their petroleum and mineral potential. It also describes the evolution of basin fluids through time. Applied Sedimentology is written principally for senior undergraduate and postgrad- uate students of earth science and engineering.
I also hope, however, that it may prove useful to more mature readers who explore and exploit the sedimentary rocks for fossil fuels and mineral deposits.
