Sedimentary rocks

Bauxite, an aluminium ore, is the world's main source of aluminium.

Marl or marlstone is a calcium carbonate or lime-rich mud or mudstone which contains variable amounts of clays and silt.

Diatomaceous earth (pronunciation: /ˌdaɪ.ətəˌmeɪʃəs ˈɜːrθ/), also known as D.

Torbanite, also known as boghead coal, is a variety of fine-grained black oil shale.

Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the Earth's surface and within bodies of water.

Sintering is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.

Clay is a fine-grained natural rock or soil material that combines one or more clay minerals with traces of metal oxides and organic matter.

In geology, a facies (pronounced variously as /ˈfeɪʃiːz/, /ˈfeɪsiːz/ or /ˈfæʃiːz/ ['faysheez', 'fayseez' or 'fash-eez']; plural also 'facies') is a body of rock with specified characteristics, which can be any observable attribute of rocks such as their overall appearance, composition, or condition of formation, and the changes that may occur in those attributes over a geographic area.

Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen.

Sedimentary Geology is a peer-reviewed scientific journal about sediments in a geological context published by Elsevier.

Loess (pronunciation: /ˈloʊ.əs/, /ˈlʌs/, /ˈlɛs/, or UK /ˈlɜːrs/; from German Löss [lœs]) is a clastic, predominantly silt-sized sediment that is formed by the accumulation of wind-blown dust.

Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O.

Particle size, also called grain size, refers to the diameter of individual grains of sediment, or the lithified particles in clastic rocks.
