The Skiddaw Group are the oldest rocks in the Lake District. They were formed as black muds and sands settling on the seabed about 500 million years ago. They have since been raised up and...

The geology of England's Lake District is dominated by sedimentary and volcanic rocks of mainly Ordovician age underpinned by large granitic intrusions. Younger sedimentary sequences outcrop on the edges of the Lake District area, with Silurian to the south, Carboniferous to the north, east, and west and Permo- Triassic to the west and east.

Jan 17, 2024 · The boundary between the volcanic rocks of the Borrowdale Volcanics and the southern sedimentary rocks is marked by a thin band of limestone that runs just south of the Old Man of Coniston, and then the Windermere Supergroup cuts a line broadly heading east from the top of Windermere.

Dec 28, 2010 · The southern third of the Lake District consists of slates, siltstones and sandstones. Called the Windemere Group, these rocks formed at the bottom of the ocean about 420 million years ago.

Geology, rocks and minerals. The Lake District was once at the bottom of the deep Iapetus Ocean, south of the Equator. Around 460 million years ago, the fusion of the three continents...

Small inliers in the Lake District have been mapped at Black Combe, Ravenglass, Furness, Bampton, and Ullswater. Correlations have been made with similar rocks east of the Eden Valley. As our oldest rocks the Skiddaw Group provides the first direct evidence for events in the Lake District but as is often the case some key information is missing ...

A glance at any geological map of the Lake District, at anything other than the smallest of scales, will reveal multitudes of faults. Faults have been created in many phases of Lake District history.

Dec 7, 2023 · Sedimentary: Limestone - limestone is probably the main type of sedimentary rock found mainly in the southern parts of the Lake District, Limestone has had a role in shaping the landscape. The presence of limestone is associated with distinctive features such as caves, cliffs, and pavements.

Most impressive of the features that make up the glacial topography in the Lake District are the glacial troughs traditionally referred to as U-Shaped valleys but many object to this nomenclature as they are commonly parabolic in section.

In the northern part of the ‘paratectonic zone’ Lower Palaeozoic rocks are exposed in three areas, namely: 1, Tremadoc to Pridoli rocks in the Lake District, known to be south of the Iapetus suture from the Caradoc and Ashgill benthic faunas; 2, Arenig to...
