Eocene clay is the host rock, forming rapidly-eroding cliffs and mud-flows onto the beach. Gypsum crystals can be found embedded in the clay, the best places to find these are in the mudflows, where the mud has caked, it is easy to see the crystals poking out. They are quite easy to find, although some of them have trapped mud particles within, which makes them look dirty even when you have cleaned them as much as you can! The other mineralogical find here is the 'barite roses' - balls of barite crystals that form within the cracks of phosphate-rich nodules. The nodules are found either in situ within the clay (but it can be very dangerous going near or up the cliffs), or more easily in the boulder fields on the beach as shown in the photographs. It is best to walk west along the beach until you go around the headland seen in the photos, you can see boulders strewn around, and some collapsed WW2 gun emplacements. Going beyond this point is the best place for the barite, but BE VERY CAREFUL OF THE TIDES and make sure you allow yourself enough time to get back. Also, be warned - you will get covered in mud!
The best crystals are found in boulders which have a brick-red outer colour. Hit with a hammer, the boulder should shatter instantly if the inside contains sizeable cracks. If it doesn't shatter immediately - move on - there will be nothing inside it, and you'll just be wasting your energy.
