The spectacular scenery of the Yorkshire Dales is a direct result of the area’s unique geology – predominantly carboniferous limestone (including Great Scar Limestone and the “Yoredale Series” of layered limestones interspersed with shales and sandstones), capped on the higher fells by Millstone Grit.
What is the main type of rock found in Yorkshire?
The solid geology of Yorkshire is dominated by rocks of the Carboniferous to Cretaceous systems (Figure 1). The hills and dales of the Pennines in the west, together with the industrial cities of the centre and south, are underlain by Carboniferous rocks.
What are the two main rock types in Yorkshire Dales?
Lying deep underground throughout the majority of the Dales is a foundation block of stone called the ‘Askrigg block’. This is formed of ancient sandstones, slates and gritstone, as well as some granite (which, unlike sedimentary rocks, is an ‘igneous’ rock created from once molten magma).
What rock is common in the Yorkshire Dales?
limestone
The majority of natural cliffs in the Yorkshire Dales occur in limestone areas, predominantly in the South of the National Park.
What are the Yorkshire Dales made of?
Limestone
Limestone Landscapes
The Dales as they are today were primarily formed by glaciation and the natural weathering of the carboniferous limestone that characterises much of the area. The limestone itself is a sedimentary rock and it was formed during the Carboniferous Period around 340 million years ago.
What stone are Yorkshire houses made from?
sandstone
Yorkshire stone, also commonly referred to as Yorkstone, is a type of sandstone that originates from quarries in Yorkshire. The natural stone is classified as a carboniferous sedimentary rock and is comprised of quartz, mica, feldspar, clay and iron oxides.
What stone is used in West Yorkshire?
Sandstone
Sandstone Mineralogy
The Carboniferous sandstones found in the buildings of west Yorkshire are all detrital, clastic rocks whose grains are derived from the weathering and breakdown of pre-existing siliceous rocks.
What gemstones can be found in Yorkshire?
From a collector’s point of view Yorkshire has been somewhat overshadowed by its more famous northern neighbours yet it has produced some excellent finds of fluorite and barite plus various secondary minerals. including smithsonite, cerussite, pyromorphite, ktenasite, gearksutite, azurite, malachite and otavite.
Why are there so many stone walls in Yorkshire?
Most walls are built to mark field boundaries or mark land ownership, and limit movement by sheep and cows. Tom Lord of Lower Winskill Farm, Langcliffe has over seven miles of dry-stone walls on his farm, some of which date back to the 13th century and are believed to have been built to deter wolves!
What type of rock is Malham?
limestone
Malham Cove is a spectacular natural limestone formation which comprises a curved limestone cliff at the head of a valley. The limestone pavement at the top is a superb example of later karst weathering.
How do I identify my rock?
Possibilities include:
- Your state geological survey.
- A natural science museum.
- A college or university with a geology department.
- A rockshop.
- Members of a local Gem & Mineral club or Rockhunting club (many hobbyists are experts at identification)
- Vendors at a Gem & Mineral show.
What is the rock in Whitby?
The Whitby Mudstone is a Toarcian (Early Jurassic; Falciferum-Bifrons in regional chronostratigraphy) geological formation in Yorkshire and Worcestershire, England. The formation, part of the Lias Group, is present in the Cleveland and Worcester Basins and the East Midlands Shelf.
What is the most common rock to find?
sedimentary rock
The most common rock on the surface of the Earth is sedimentary rock. These rocks cover about 75% of the Earth’s surface. The surface of the Earth, however, is only a very small part of the crust of the Earth. Under the crust, 95% of the rocks are igneous or metamorphic rocks.
What makes Yorkshire unique?
The Yorkshire Dales encompasses 680 square miles and is home to outstanding scenery, great castles, abbeys and a breathtakingly peaceful atmosphere. They are visited by around eight million tourists a year because of their stunning tranquility and natural beauty.
How was Yorkshire Dales formed?
The bones of the Yorkshire Dales were formed in water when tropical seas and giant river deltas laid down the rocks of the area millions of years ago. Frozen water shaped the valleys and scraped clean our famous limestone pavements during the Ice Ages.
What is Yorkshire most famous for?

How do I identify a Yorkshire stone?
The Facts
- Flaky paving – check the surface of the paving for loose ridges and flakes.
- Missing corners.
- Paint, oil or mortar stains.
- Roofing tiles sold as paving flags.
- Irregular shapes – some flagstones may be not be rectangular, making them very hard to lay.
Is Yorkshire stone porous?
Yorkstone is porous in consistency – which is why it varies in colour – but this also means it is an excellent heat conductor.
How was Yorkshire stone formed?
Yorkstone was formed over 300 million years ago. It was formed during the ‘coal bearing’ period, also known as the Carboniferous period. Yorkstone consists of mica, quartz, iron, feldspare, silica, clay and iron oxides. A huge industry has been created around quarrying the York stone material.
What are Yorkshire dry stone walls made of?
Nowell’s Limestone Moss is confined to seven sites all within the Yorkshire Dales, several of the sites being drystone walls in the vicinity of Pen-y-ghent. It is a brownish-green moss that forms dense cushions. The moss is named after John Nowell, who first discovered the species in 1866.
What is the most common stone in the UK?
In general terms, limestone predominates in southern Britain and sandstone in the north, but some limestones such as Portland stone have been used ubiquitously; and some sandstones, for example York stone are widely used especially for paving.
