Where is sedimentary rock found in the uk
For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica as interlocked crystals; a sandstone is a sedimentary rock that can also contain quartz, feldspar and mica, but as grains compacted and cemented into each other.
The definition of an economic mineral is broader. Economic minerals are extracted from the Earth by quarrying, mining and pumping and used in a wide range of applications related to construction, manufacturing, agriculture and energy supply.
They include:. Visit the MineralsUK website for more information about economic minerals. Discovering Geology introduces a range of geoscience topics to school-age students and learners of all ages. Planet Earth is dynamic with a surface that is always changing. Find out about the processes that cause these changes. Climate is the pattern of weather of an area averaged over many years. We can only show whether climate change has occurred after decades of careful measurements and analysis.
The Earth beneath our feet is constantly shifting and moving, and violently with catastrophic and immediate results. Find out more about earth hazards. Take a look at the history of the Earth, from its formation over four and a half billion years ago to present times.

There are three main types of rock, classified by how they are sourced and formed: sedimentary igneous metamorphic. Sedimentary rocks Sedimentary rocks are recycled rocks formed by the deposition of fragments of material sediment that have been eroded and weathered from other parent rocks. Horizontal layering of sedimentary rocks.
Towards the top of the picture there is a layer of sedimentary rock made up of sand and pebbles known as a conglomerate , deposited between finer-grained that is, made up of smaller fragments rocks. The geological hammer is for scale. Igneous rocks Igneous rocks are formed by the cooling of a very hot, molten material called magma, which originates deep inside the Earth.
A flow of lava cooled down slowly, developing cracks known as joints that created the basalt columns. Granite from Peterhead in Scotland.

Sedimentary rocks — these are made up of small particles of sand and rock, which have been transported by the wind, rivers and ice and are usually deposited on lake or seabed. Over many millions of years, successive layers of sediments accumulate.
These layers of sediments are compressed by the weight of the deposits above, into sedimentary rocks. These rocks form in layers, known as bedding planes.
When sand is compressed it forms sandstone. When mud is compressed it becomes clay.
