    Sedimentary rocks can be divided into two major categories: clastic and precipitated (or chemical). Since the character of the sedimentary rock is largely controlled by the sedimentary environment, they have a story to tell about the climate, the environment, and even who lived at the time they were laid down. Reading the book of sedimentary ...

  • Clastic Sedimentary Rock Classification

    Sedimentary rocks are classified on the basis of the texture (grain size) of the rock, and composition. The basic classification only concerned texture, using the Wentworth size scale.But any full rock name must specify both texture and composition. Thus, an arkose sandstone is a rock of sand sized particles, with a high percentage of those particles being feldspar.

  • Sedimentary Rocks | Geology

    Sedimentary rocks formed by the crystallization of chemical precipitates are called chemical sedimentary rocks. As discussed in the "Earth's Minerals" chapter, dissolved ions in fluids precipitate out of the fluid and settle out, just like the halite in Figure 5. Biochemical sedimentary rocks form in the ocean or a salt lake. Living ...

    Other Characteristics: low hardness and reactivity to acid of calcite combined with the dripstone structure (stalagmites and stalactites) of the rock ; KAOLIN. Kaolin is a sedimentary rock composed of white kaolinite clay. This aluminum-rich rock is an aluminum ore commonly used in ceramics, paints, paper, and other products.

  • Rock Types: Igneous, Sedimentary & Metamorphic Rocks | .

    Dec 28, 2015 · Sedimentary rocks are not as rich in minerals of economic value as the igneous rocks. But important minerals such as hematite iron ore, phosphates, building stones, coals, petroleum and material used in cement industry are found.

  • sedimentary rock | Organic-rich sedimentary deposits ...

    sedimentary rock - Organic-rich sedimentary deposits - Coal, oil shale, and petroleum are not sedimentary rocks per se; they represent accumulations of undecayed organic tissue that can either make up the bulk of the material (e.g., coal), or be disseminated in the pores within mudrocks, sandstones, and carbonates (e.g., oil shale and petroleum).

  • Limestone - Sedimentary rocks

    Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or .

    Flint: a variety of chert which is dark owing to the presence of carbon-rich material. Evaporites - chemical sedimentary rocks that form through the evaporation of water; usually found in dry lake beds (playas). Rock salt, rock gypsum, are two examples. Coal - organic sedimentary rock composed of the remains of plant material. Various grades of ...

    Bauxite is an aluminum-rich sedimentary rock. It is a principal ore of aluminum. Aluminum in bauxite is hosted by aluminum hydroxide minerals, mostly gibbsite. The major impurities are iron oxides and hydroxides (which give reddish color to most bauxites) and clay minerals.

    Rock Salt is a chemical sedimentary rock that forms from the evaporation of ocean or saline lake waters. It is also known by the mineral name "halite."It is rarely found at Earth's surface, except in areas of very arid climate. It is often mined for use in the chemical industry or .

  • Sedimentary rock - Iron-rich sedimentary rocks ...

    Sedimentary rock - Sedimentary rock - Iron-rich sedimentary rocks: Almost all sedimentary rocks are iron-bearing in the sense that mudrocks, sandstones, and carbonates typically have an iron content of several percent. Nevertheless, sedimentary rocks in which the proportion of iron exceeds 15 percent are separately categorized as iron-rich.
