What are the 3 main types of rock in the UK?
There are three main types of rock, classified by how they are sourced and formed: sedimentary. igneous. metamorphic.
What rock is the UK mostly made up of?
The geology of England is mainly sedimentary. The youngest rocks are in the south east around London, progressing in age in a north westerly direction.
Where can we find metamorphic rocks?
Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. This happens due to geologic uplift and the erosion of the rock and soil above them. At the surface, metamorphic rocks will be exposed to weathering processes and may break down into sediment.
How many types of metamorphic rocks are there?
There are two main types of metamorphic rocks: those that are foliated because they have formed in an environment with either directed pressure or shear stress, and those that are not foliated because they have formed in an environment without directed pressure or relatively near the surface with very little pressure …
What are igneous and metamorphic rocks?
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
Where are metamorphic rocks found?
We often find metamorphic rocks in mountain ranges where high pressures squeezed the rocks together and they piled up to form ranges such as the Himalayas, Alps, and the Rocky Mountains. Metamorphic rocks are forming deep in the core of these mountain ranges.
Where is flint found in UK?
Puzzling giant flint formations known as paramoudra and flint circles are found around Europe but especially in Norfolk, England on the beaches at Beeston Bump and West Runton.

Working slate quarry at Delabole, Cornwall.
What are the different types of metamorphic rocks?
Slate is another common metamorphic rock that forms from shale. Limestone, a sedimentary rock, will change into the metamorphic rock marble if the right conditions are met. Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth.
What is contact metamorphism in geology?
Contact Metamorphism: A type of local, thermal metamorphism caused by the intrusion and extrusion of magmas; takes place in rocks at or near their contact with a body of igneous rock. Parent Rock: Rock from which soil, sediment, or other rock is derived.
What is the oldest type of rock in Britain?
The oldest rocks in Britain are found in NW Scotland and the western isles. This ancient Lewisian gneiss is almost 3,000 million years old! The Scottish Highlands are mainly formed from metamorphic rocks formed around 400-450 million years ago.
