“…The latter resulted in the progressive flooding of landmasses surrounding the Early Cretaceous North Sea Basin (Ziegler 1990). At the end of the Early Cretaceous, sea level exceeded present-day levels by 100-300 m (Albian transgression ;Hancock 1975) which enabled initial deposition of the Chalk Group in the North Sea Basin (Ziegler 1990).…”

“…The latter resulted in a reduced influx of detritus and enabled pelagic sedimentation on the continental shelves, including the North Sea area (Surlyk et al 2003). The water depth estimated for the Chalk Group probably ranged between a 100 m on the shelf and a few 100 m in the deep-water areas of the North Sea (Hancock 1975;Surlyk et al 2003). The thickness of the Chalk Group in the Southern Permian Basin ranges between <150 and more than 1800 m showing regional maxima within the North Sea Central Graben (Vejbaek et al 2010).…”

“…It is an extremely pure marine limestone that accumulated in the North Sea Basin to a thickness of up to 886 m (Hancock 1975, Gale 2000. It is probable that when it was deposited Britain, with the possible exception of a few islands in high-altitude locations, suffered almost total submergence (Fig.…”

AbstrAct. Substantial parts of the British Isles preserve landscapes that are the legacy of pre-Quaternary times. Some of these may be the result of burial and exhumation of pre-Cenozoic features. However, most landscapes post-date the Cretaceous transgression during which a Chalk mantle was laid down. Much of the British Isles became land during the Palaeogene and the Chalk cover was rapidly removed over large areas. Sea floor spreading, thermal uplift, and intrusion and extrusion of igneous material occurred. Landscapes also evolved in response to warm climatic conditions and this may have led to etchplanation. In the Neogene various surface formed and were affected by ongoing tectonic activity. Various estimates have been made of Cenozoic denudation rates and amounts, but they appear to have varied spatially and temporally. Landscapes which provide tangible evidence of pre-Quaternary times include those of north-east Scotland and southern England. Such ancient landscapes are important components of the Geoheritage of Britain.

“…The grainy textures of many chalks, especially in the Lewes Nodular Chalk and the Holywell Nodular Chalk, in large part reflect a concentration of minute calcite prisms derived by the comminution of inoceramid bivalve shells. Studies by scanning electron microscope has shown that other chalks are dominated by coccoliths, or calcispheres or other types of microfossil material (Hancock, 1975;Mortimore et al, 2001). …”

Abstract:The modern Chalk Group lithostratigraphy divides the Chalk of southern England into nine formations, each with a characteristic lithological assemblage. It is more useful than the traditional subdivision into Lower Chalk, Middle Chalk and Upper Chalk because it can be applied more consistently over a wider area, it provides a better indication of lithological variation, it allows the recognition of more tectonic structures and it is thus more useful for practical application in engineering geology and hydrogeology.The process of surveying the Chalk that has been developed by the British Geological Survey over the past two decades is an empirical modification of the traditional methods used for detailed geological survey of sedimentary sequences in other parts of the United Kingdom. Each Chalk formation is closely associated with characteristic landforms, allowing them to be mapped with reasonable consistency and accuracy in largely unexposed ground and through built-up areas. This association of landform and lithostratigraphy reflects the response to weathering (and other surface processes) of relatively subtle variations in bulk lithological assemblage, rather than of individual beds of contrasting lithology.
