Isolated island of 17x12 kmn in the centre of which is a volcano with a summit height of 655m. Most of the island is built of leucite-bearing basanitic, trachybasanitic and tephritic lava flows. There are 44 domes and plugs of phonolite, which contain nepheline but free of leucite.

Geochronology

Mineralization age: Pleistocene : 0.84 Ma to 0.26 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality 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.
