Sedimentary Rocks

Sedimentary Rocks are formed from sediment which has settled at the bottom of rivers, lakes and oceans. Layer after layer of sediment is deposited on top of each other, then through time each layer is compressed down more and more, until the bottom layers slowly turn into a solid form of rock. Common types include Limestone, Mudstone, Shale, and Sandstone.

Limestone

Provided loose in 1kg bags

Limestone is mostly composed of calcite and aragonite. A large number of limestone's are composed from the skeletal fragments of marine organisms. For example: corals or foraminifera. Limestone's react strongly with acids, and are soluble in water, this means they erode quickly. Cave systems are often formed from limestone rock.

Sandstone

Provided loose in 1kg bags

Sandstone is a sedimentary rock composed mainly of sand-sized minerals or rock grains. It is mostly composed of quartz or feldspar, and can be any colour, but the most common colours are brown and red.

Chalk

Provided loose in 1kg bags

Chalk is a porous rock which is a type of limestone. It is composed of calcite which is formed under deep marine conditions, by the build up of the calcite shed from coccolithophores. Chert and Flint are commonly found embedded in chalk.

Mudstone

Provided loose in 1kg bags

Mudstone is a fine grained sedimentary rock, of which it originated from clays or muds. The individual grains are too small to be distinguished without a microscope. Mudstone looks like hardened clay and can sometimes show cracks or fissures. It can be surprisingly hard.

Shale

Provided loose in 1kg bags

Shale is composed of mud which is a mixture of clay minerals and fragments of other minerals. Shale can be both marine or non-marine, and often has the highest concentration of fossils. For example: the famous fossils of the Jurassic Coastline all come from shale beds.

Coal

Provided loose in 1kg bags

This common fossil fuel actually originated from England, being an old English word 'Col' meaning mineral of fossilised carbon. It usually occurs in seams. Coal is composed primarily of carbon, and is found in the Carboniferous period.

Oolite

Provided loose in 1kg bags

Oolite is formed from ooids, which are spherical grains composed of concentric layers. Oolite is defined as having ooids of between 0.25-2mm diameter. Any larger and the rock is a pisolite. Common types of these rocks are the "Inferior Oolite" and the "Great Oolite" series, which are Jurassic in age.

Conglomerate

Provided loose in 1kg bags

A conglomerate is a rock which consists of individual clasts within a finer-grained matrix that have become cemented together. These consist of rounded fragments unlike breccias which have angular clasts. Clasts are larger than 2 mm.

Clay

Provided loose in 1kg bags

Clay is an extremely fine rock, mostly composed of phyllosilicate minerals containing a variable amount of water trapped in the mineral structure. Common Clays include the Frome Clay, Oxford Clay, Kimmeridge Clay and Gault Clay, which are all rich in fossils.
