Chalk Downs, pale green (6) Geological section from north to south The geology of East Sussex is defined by the Weald–Artois anticline , a 60 kilometres (37 mi) wide and 100 kilometres (62 mi) long fold within which caused the arching up of the chalk into a broad dome within the middle Miocene , [ 1 ] which has subsequently been eroded to ...
Chalk is so common in Cretaceous marine beds that the Cretaceous Period was named for these deposits. The name Cretaceous was derived from Latin creta, meaning chalk. [10] Some deposits of chalk were formed after the Cretaceous. [11] The Chalk Group is a European stratigraphic unit deposited during the late Cretaceous Period.
Kevin Lygo, the show's executive producer and head of Independent Commissions Entertainment, who commissioned the series defending the show from the union's criticisms, saying: "Chalk is a comedy. Just as Ben Elton's Thin Blue Line does not reflect the modern police force nor The Vicar of Dibley the Church of England today, Chalk was never ...
The chalk formation of the hills provides exceptionally good drainage, with the result that most of these valleys are dry; indeed, surface water is quite scarce throughout the Wolds. Typically the valleys are hard to see from above, creating the visual impression that the landscape is much flatter than is actually the case.

The chalk and water mixture, also called Kreidemilch or Kreidetrübe, was passed through separation tanks where the finer impurities, the Grand, settled out. The chalk suspension freed from the grand finally ended up in the settling basin, in which the still-suspended particles settled out and accumulated into a layer about 30 cm thick. The now ...
The crust formed on the lid was ground to powder and boiled with water to remove the calomel. Calx – calcium oxide; was also used to refer to other metal oxides. Chalcanthum – the residue produced by strongly roasting blue vitriol (copper sulfate); it is composed mostly of cupric oxide. Chalk – a rock composed of porous biogenic calcium ...
The chalk was formed in the Late Cretaceous epoch, between 66 and 100 million years ago, when the area was under the sea. During the Cenozoic Era, the chalk was uplifted (see Cenozoic Era). When the last ice age ended, sea levels rose and the English Channel formed, cutting into the chalk to form the dramatic cliffs along the Sussex coast.
