The erosion of this landscape by carbonation has led to very distinctive scenery. Particularly notable is the area around Malham in the Yorkshire Dales with its limestone pavements, sink holes and shake holes. Gaping Gill contains a waterfall disappearing underground into the Carboniferous limestone.
Limestone was also a very popular building block in the Middle Ages in the areas where it occurred, since it is hard, durable, and commonly occurs in easily accessible surface exposures. Many medieval churches and castles in Europe are made of limestone. Beer stone was a popular kind of limestone for medieval buildings in southern England. [109]
The larger part of the national park is formed in sedimentary rocks from the Carboniferous period (359 - 299 Ma). In stratigraphic sequence i.e. youngest at the top, the sequence consists of: [3] Pennine Coal Measures Group; Millstone Grit Group; Yoredale Group (Asbian - Yeadonian) Stainmore Formation; Alston Formation (inc Gayle Limestone ...
A rock formation is an isolated, scenic, or spectacular surface rock outcrop. Rock formations are usually the result of weathering and erosion sculpting the existing rock. The term rock formation can also refer to specific sedimentary strata or other rock unit in stratigraphic and petrologic studies.
A limestone pavement is a natural karst landform consisting of a flat, incised surface of exposed limestone that resembles an artificial pavement. [1] The term is mainly used in the UK and Ireland, where many of these landforms have developed distinctive surface patterning resembling paving blocks. [ 2 ]
Tepee buttes form as small, conical hills in the Pierre shale landscape, from lenses of more erosion resistant limestone. Beach sand coal sequences left behind as the up to 200 feet thick Fox Hills Formation after the Western Interior Seaway began to recede, 15 million years after the Pierre shale first started to form.
The Pancake Rocks are a heavily eroded limestone formation where the sea bursts through several vertical blowholes during incoming swells, particularly at high tide. The limestone was formed in the Oligocene period (around 22–30 million years old), a period in the geological history of New Zealand where most of the continent of Zealandia was submerged beneath shallow seas.
