In geology, clay-with-flints is the name given by William Whitaker in 1861 to a peculiar deposit of stiff red, brown, or yellow clay containing unworn whole flints as well as angular shattered fragments, also with a variable admixture of rounded flint, quartz, quartzite, and other pebbles. [1]
Silt – Soil type consisting of fine grain deposits that offer good water retention but poor drainage. It is more fertile than sand. Silex – A flint- and sand-based soil type found primarily in the Loire Valley that is a formed from a mixture of clay, limestone and silica. [2] Slate – Soil type that is the most common found in the Mosel ...
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.
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 ...
Depending on the environmental conditions present at the time of their formation, concretions can be created by either concentric or pervasive growth. [11] [12] In concentric growth, the concretion grows as successive layers of mineral precipitate around a central core. This process results in roughly spherical concretions that grow with time.
When the soil dries out, it contracts vertically, assisting the soil slowly down a slope. [5] A common geomorphological, chiefly dependent on the local hydrology such as hydraulic action, at the base of the Lower Greensand is an escarpment, where the Hythe Beds overlie the Atherfield and Weald Clays, which is particularly susceptible to ...
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 rocks that formed in the Pennsylvanian and Permian were mainly terrestrial in origin, including non-marine shale, sandstone, coal, ironstone and limestone, along with some marine rocks, such as flint and marine shale. River deltas in the Pennsylvanian, were covered in thick, swampy vegetation, helping to produce coal deposits.
