It is of early to mid-Thanetian (late Paleocene) age and gave its name to that stratigraphic interval.
The Thanetian was first proposed by Swiss geologist Eugène Renevier, in 1873; he included the south England Thanet, Woolwich, and Reading formations.

It is of early to mid-Thanetian (late Paleocene) age and gave its name to that stratigraphic interval.
The Thanetian is named after the Thanet Formation, the oldest Cenozoic deposit of the London Basin, which was first identified in the area of Kent (southern England) known as the Isle of Thanet.

London Basin

The Thanet Formation is a geological formation found in the London Basin of southeastern England.
The lowest (oldest) unit is the Thanet Formation (of Thanetian age, 56 – 58 million years old ), which rests unconformable on top of the Chalk.

To the west it is missing, with the Lambeth Group lying directly on the Chalk, and to the north it is replaced by the Ormesby Clay Member.
Except in the Hampshire Basin, the Lambeth Group usually rests on the Thanet Formation of the Montrose Group, but is found on the Chalk Group near Bromley, Charlton, Hungerford, Hertford and Reading.

Eddington is approximately 13 metres above sea level, lying above mainly London Clay with some head Brickearth next to Plenty Brook; however to the east this changes to Tertiary deposits of the Thanet, Oldhaven and Woolwich beds.

Reculver

Reculver Castle
In the 20th century twelve wells of the Roman period were identified to the west of the fort, ten of which were square; all were cut into the hard layer of sandstone below the soft sandstone of the Thanet Beds, thus tapping into the water table.
