The Formation is associated with deposits of the Chalk Group, subsequent Palaeogene and Neogene strata, and occasionally Upper Greensand. [2] It occurs in sheets or patches of various sizes over a large area in the south of England, from Hertfordshire on the north to Sussex on the south, and from Kent on the east to Devon on the west.
Flint mining is the process of extracting flint from underground. Flint mines can be as simple as a pit on the surface or an area of quarrying, or it may refer to a series of shafts and tunnels used to extract flint. Flint has been mined since the Palaeolithic, but was most common during the Neolithic.
Flint, occasionally flintstone, is a sedimentary cryptocrystalline form of the mineral quartz, [1] [2] categorized as the variety of chert that occurs in chalk or marly limestone. Historically, flint was widely used to make stone tools and start fires. Flint occurs chiefly as nodules and masses in sedimentary rocks, such as chalks and limestones.
The route to the southern end of the flint fields is a well maintained and picturesque woodland path which branches off the old B 196a federal road immediately north of the caravan park (former traffic testing area). The nearest railway stop is Prora, around 2½ kilometres south of the area and five hundred metres south of the traffic testing area.
Flint clay can be either detrital or authegenic in origin. Detrital flint clays consist of kaolinite-rich sediments eroded and transported from uplands deeply weathered under tropical climates and redeposited within the coastal plains, in which coal-bearing strata accumulated.
The original soil surface is buried, and the formation process must begin anew for this deposit. Over time the soil will develop a profile that depends on the intensities of biota and climate. While a soil can achieve relative stability of its properties for extended periods, [ 117 ] the soil life cycle ultimately ends in soil conditions that ...
