TAB48XXX: Two groups of Baryte crystals, one of them forming a rosette aggregate of cream color and the other a fibrous-radial aggregate, possibly replacing a fossil shell and preserving its original structure, with the terminations being more whitish. They are on a matrix of very fine-grained clayey rock, whitish, completely covered by cream-colored Calcite crystals of a darker tone and lustrous, partially coating a botryoidal aggregate with another possible fossil shell.

Warden Bay is a coastal area known for its Eocene clay cliffs (London Clay Formation), rich in fossils and concretions. It is a classic locality for the occurrence of Baryte and Pyrite nodules and crystals, formed under reducing sedimentary conditions, often associated with organic remains.
