Chalk boulders at the base of Shakespeare Cliff on beach to the east of the car park and Channel Tunnel works at Samphire Hoe.

This locality is frequently referred to as "Samphire Hoe", more for convenience than through accuracy. Samphire Hoe is 'reclaimed' land produced by dumping the waste rock from the digging of the Channel Tunnel, and this is mostly landscaped and enclosed within thick concrete and rock sea defences now.

However, the access tunnel and car park (£2 per day parking as of 2017) at Samphire Hoe do provide very convenient access for the beach areas to the east and west where mineral specimens and the occasional cretaceous fossil may be collected.

Generally the beach area under the cliffs immediately to the (north) east of the Samphire Hoe area is the best area for collecting. This beach cannot be accessed at high tide, and you must be careful not to go too far along the beach here in case you are caught by the tide turning.

The marker on the map shows the starting point on the beach where good material can be found. You do not need to go very far from this point to find things.

Due to the constant erosion there is a virtually unlimited supply of material.

Geochronology

Mineralization age: Late Cretaceous : 100.5 Ma to 66.0 Ma

Important note: This table is based only on rock and mineral ages recorded below and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
