Description

Area, 0.38 ha. 0.94 ac. Description This pit shows the thickest and the stratigraphically most important Lower Gault sequence in the country and is a vital collecting ground for the eodentatus to daviesi Subzone faunas. The quarry is also the type locality of the Horton Wood Clay of regular is Subzone age which is a local and unusual development of the upper Folkestone Beds. The lithological and stratigraphic evidence from Horton is important in showing the sedimentary evidence of a major structural basin which controlled Lower and Middle Albion sedimentation in the Western Weald.
