The Upper Greensand Formation is a Cretaceous formation of Albian to Cenomanian in age, found within the Wessex Basin and parts of the Weald Basin in southern England. [1] It overlies the Gault Clay and underlies the Chalk Group. It varies in thickness from zero to 75 m. It is predominantly a glauconitic fine-grained sandstone, locally becoming ...
Greensand or green sand is a sand or sandstone which has a greenish color. This term is specifically applied to shallow marine sediment that contains noticeable quantities of rounded greenish grains. These grains are called glauconies and consist of a mixture of mixed-layer clay minerals, such as smectite and glauconite. Greensand is also ...
tr This is a list of stratigraphic units from which dinosaur body fossils have been recovered. Although Dinosauria is a clade which includes modern birds, this article covers only Mesozoic stratigraphic units. Units listed are all either formation rank or higher (e.g. group).
Upper Greensand Hangers: Wyck to Wheatley is a 13.2-hectare (33-acre) biological Site of Special Scientific Interest east of Alton in Hampshire. [1] [2] It is part of the East Hampshire Hangers Special Area of Conservation. [3] This site is composed of woods on the steep rocky slopes of the Upper Greensand.
The oldest strata to outcrop at the surface within West Sussex are the sandstones and siltstones of the Ashdown Formation of the Purbeck Group which date from around 146-134 million years ago. The younger Upper Cretaceous is represented by the rocks of the Chalk Group, overwhelmingly the characteristic fine-grained white limestone known as chalk.
The Greensand Ridge, also known as the Wealden Greensand, [1] is an extensive, prominent, often wooded, mixed greensand/sandstone escarpment in south-east England. Forming part of the Weald , a former dense forest in Sussex, Surrey and Kent, it runs to and from the East Sussex coast, wrapping around the High Weald and Low Weald.

Geological map of the Isle of Wight. The geology of the Isle of Wight is dominated by sedimentary rocks of Cretaceous and Paleogene age. This sequence was affected by the late stages of the Alpine Orogeny, forming the Isle of Wight monocline, the cause of the steeply-dipping outcrops of the Chalk Group and overlying Paleogene strata seen at The Needles, Alum Bay and Whitecliff Bay.
