The general process for writing rock descriptions is to start off with a general description (general colour, grain size, texture..), followed by identification of the minerals within the rock (the mineral assemblage), the name of the rock (deduced from the assemblage) and then finally your best guess on how and where it was formed , source: Introducing Sedimentology (Introducing Earth and Environmental Sciences) download online Introducing Sedimentology (Introducing Earth and Environmental Sciences).

Sandstones are divided into two broad groups: arenites, containing little or no matrix (< 5 percent), and wackes, containing perceptible matrix. Combining the matrix parameter with composition (QFL, see Fig. 4.12 for explanation) yields six kinds of sandstones: quartz arenites and wackes, feldspathic arenites and wackes, and lithic aenites and wackes. The two classifications shown in Fig. 4.13 are examples of the second type of classification Tracking Environmental Change Using Lake Sediments: Volume 1: Basin Analysis, Coring, and Chronological Techniques (Developments in Paleoenvironmental Research) download Tracking Environmental Change Using Lake Sediments: Volume 1: Basin Analysis, Coring, and Chronological Techniques (Developments in Paleoenvironmental Research) here.

Hydrostatic pressures at a particular depth are typically much lower than geostatic pressures (commonly less than about one-half). On the other hand, pore fluids trapped in sediments during compaction or in sediments subjected to tectonic stresses may develop abnormally high hydrostatic pressures , source: Sedimentary Geology, read online read online Sedimentary Geology, International Journal of Applied and Regional Sedimentology, 1984, Sedimentary Geology, 39 (1/2) :.. Quartz tends to be more abundant in coarser-grained mudstones and shales, whereas clay minerals are more abundant in finer-grained mudstones and shales. 206 Mudstones and shales Table 6.2 Principal constituents in shales and mudstones Constituents Silicate minerals Quartz Remarks Makes up 20 to 30 percent of the average shale; probably mostly detrital; chalcedony and biogenic opal-A and opal-CT may also be present Commonly less abundant than quartz; plagioclase generally more abundant than alkali feldspars Commonly present as an alteration product of volcanic glass; phillipsite and clinoptilolite are common zeolites in modern marine sediments Forms under strongly leaching conditions: abundant rainfall, good drainage, acid waters; in marine basin tends to be concentrated nearshore Smectite is a hydrated, expandable clay; common in soils and as an alteration product of volcanic glass; alters to illite during burial; illite is the most abundant clay mineral in shales; derived mainly from pre-existing shales; alters to muscovite during diagenesis; muscovite may also be detrital Chlorite forms particularly during burial diagenesis; second in abundance only to illite in Paleozoic and older shales; during burial, vermiculite may convert to corrensite and finally to chlorite Magnesium-rich clays that form under special conditions where pore waters are rich in Mg, e.g. saline lakes Hematite most common in shales, but goethite or limonite may be more common in modern muds; commonly present as coatings on clay minerals; may be converted to pyrite or siderite in reducing environments Consists of Al(OH)3; may be associated with kaolinite in marine shales derived from the weathering of tropical landmasses More common in marine than nonmarine shales An important cementing agent in some shales Occur in shales most commonly as concretions Occur as concretions in shales and may indicate the presence of hypersaline conditions during or after deposition Mainly the iron sulfides pyrite and marcasite; these sulfides are most abundant in marine shales and indicate reducing conditions either at the time of deposition or during diagensis Feldspars Zeolites Clay minerals Kaolinite (7 Å) Smectite–illite–muscovite (10 Å and greater) Chlorite, corrensite, and vermiculite Sepiolite and attapulgite Oxides and hydroxides Iron oxides Gibbsite Carbonates Calcite Dolomite Siderite and ankerite Sulfur minerals Sulfates: gypsum, anhydrite, and barite Sulfides 6.4 Composition 207 Table 6.2 (cont.)

Thus, facies may change vertically through a sequence as a result of changing environments through time Petroleum Basin Studies download here read Petroleum Basin Studies. Each of these origins implies a low energy setting. The other four rocks you were given are clastic sedimentary rocks and you should think of where they are found within a depositional system. Conglomerate, with its large (> 2mm) clast sizes, requires a great deal of energy to move and collect and so reflects the highest energy environments Practical sedimentology click Practical sedimentology. When igneous rocks form at the earth’s surface by volcanism, and when igneous, sedimentary, and volcanic rocks are exhumed at the surface by uplift (related to mountain building and isostatic adjustment of the crust), they degrade by weathering and erosion to remain as only the most stable of the preexisting minerals, or they form new, more stable minerals altogether , source: Agricultural Salinity download online Agricultural Salinity Assessment and Management (Asce Manual and Reports on Engineering Practice) here. We can learn about the methodsof transportation, and the distance that these sediments have been transported from their original sources. We can also study depositional environments and changes in those depositional environments. Both long and short term changes are preserved in these depositional environments, and not only that, but we can often learn about ancient topography simply by understanding the drainage patterns of the ancient streams which deposited these sediments in the first place online.

Interest was rekindled in the early 1960s with the development of the concept of plate tectonics. Research on the relationship of sediment composition and tectonics has continued extremely active since that time. The basis for interpreting tectonic setting is the assumption that detrital mineralogy and geochemistry reflect not only source-rock lithology but also the general plate-tectonic setting ref.: Sedimentary Geology, International Journal of Applied and Regional Sedimentology, 1985, Sedimentary Geology, 42 (3/4) :.

Coals can thus be classified also on the basis of megascopic textural appearance and their recognizable petrographic or microscopic constituents. Transmitted-light microscopes can be used to study coals up to the rank of low-volatile bituminous.

Clay minerals are also common because the clay minerals are themselves products of chemical weathering which can be transported to new locations. The rock may also contain feldspar and other easily weathered materials if it's immature and is close to the source. Calcite crystals and grains are common here on tropical beaches, broken off fragments from shells and the reef, which are deposited on the beach, and most sediments of the clastic type also contains small grains of rarer minerals, which represent the minor or accessory minerals in the various rocks read online Generation, Accumulation and Production of Europe's Hydrocarbons III: Special Publication of the European Association of Petroleum Geoscientists No. 3 pdf, azw (kindle), epub.

Coarse micas rarely form more than about two percent of the framework grains of sandstones and commonly much less. Muscovite is chemically more stable than biotite and is much more abundant in sandstones on the average than biotite. Coarse detrital chlorite is less abundant than biotite, possibly as a result of the greater tendency of chlorite to degrade mechanically to finer-size grains Accumulation of Organic Carbon in Marine Sediments: Results from the Deep Sea Drilling Project/Ocean Drilling Program (DSDP/ODP) (Lecture Notes in Earth Sciences) read Accumulation of Organic Carbon in Marine Sediments: Results from the Deep Sea Drilling Project/Ocean Drilling Program (DSDP/ODP) (Lecture Notes in Earth Sciences) here.
