Lectures. 1. Siliciclastic sediments. – granulometric analysis, provenance and geotectonic position → modal composition, heavy minerals. – classification – see . This is the second edition of a book first published in The publisher's description on the back cover claims it to be a comprehensive text. 2nd edition. Cambridge University Press, p. ISBN This book emphasizes the properties of sedimentary rocks rather than.

This highly generalized succession of sedimentary processes leads to generation of four fundamental kinds of constituents - terrigenous siliciclastic particles, chemicallbiochemical constituents, carbonaceous constituents, and authigenic constituents - which, in various proportions, make up all sedimentary rock.

Boggs Principles of Sedimentology and Stratigraphy

The minerals are mainly silicates such as quartz, feldspars, and micas. The rock fragments are clasts of igneous, metamorphic, or older sedimentary rock that are also composed dominantly of silicate minerals. Further, fme-grained secondary minerals, particularly iron oxides and clay minerals, are generated at weathering sites by recombination and crystallization of chemical elements released from parent rocks during weathering.

Because of their largely extrabasinal origin and the fact that most of the particles are silicates, we commonly refer to them as terrigenous siliciclastic grains, although some pyroclastic particles may originate within depositional basins.

These siliciclastic grains are the constituents that make up common sandstones, conglomerates, and shales. Some precipitated minerals may become aggregated into silt- or sand-size grains that are moved about by currents and waves within the depositional basin.

Carbonate ooids and pellets are familiar examples of such aggregate grains. There is no commonly accepted group name for precipitated minerals and mineral aggregates, analogous to the term siliciclastic; they are referred to here simply as chemicallbiochemical constituents. Carbonaceous constituents The preserved, carbonized residues of terrestrial plants and marine plants and animals, together with the petroleum bitumens, make up a third category of sedimentary constituents.

Sapropelic residues are the remains of spores, pollen, phyto- and zooplankton, and macerated plant debris that accumulate in water. They are the chief constituents of cannel coals and oil shales. Bitumens are solid asphaltic residues that form from petroleum through loss of vola tiles, oxidation, and polymerization.

Authigenic constituents Minerals precipitated from pore waters within the sedimentary pile during burial diagenesis constitute a fourth category of constituents. These secondary, or authigenic, constituents may include silicate minerals such as quartz, feldspars, clay minerals, and glauconite and non silicate minerals such as calcite, gypsum, barite, and hematite.

They may be added during burial to any type of sedimentary rock but are never the dominant constituents of sedimentary rocks. As shown in Fig. Carbonaceous sedimentary rocks may be separated by composition into oil shales, impure coals, coals, and bitumens. Although we recognize many types of sedimentary rocks on the basis of composition and grain size, only three of these rock types are volumetrically important. As discussed in greater detail below, mudrocks shales , sandstones, and limestones make up the bulk of all sedimentary rocks in the rock record.

Therefore, I have placed major emphasis in this book on these two important groups of rocks. The ages of the oldest known sedimentary rocks in Greenland and northern Quebec, Canada have been determined by iron isotope analyses to be about 3. Dauphas et al.

The first rocks that formed on Earth were probably basic volcanic rocks. Sedimentary rocks began to form once Earth's atmosphere and oceans had developed owing to degassing of Earth's interior. The area of Earth's surface covered by sedimentary rocks has increased progressively with time as the area of volcanic rocks has been successively reduced by erosion Fig.

Sedimentary rocks now cover about 80 percent of the total land area of Earth Ronov, They also cover most of the floor of the ocean, above a basement of volcanic rocks, According to Ronov, sedimentary rocks make up about 11 percent of the volume 9. Average thickness of Earth's sedimentary shell is 2. Friedman et al. Boring of carbonate grains by endolithic fungi and algae is commonly most intense in shallow-water tropical areas.

If boring activities are prolonged and intense, the entire surface of a grain may become infested by these aragonite- or Mg-calcite-filled borings, resulting in the formation of a thin coat of micrite around the grain. This coating is called a micrite envelope Bathurst, The cortoids described in Chapter 9 probably formed in this way.

Even more intensive boring may result in complete micritization of the grain, with the result that all internal textures are destroyed and a kind of peloid is created.
