The island consists of c. 90% granite, emplaced into Devonian sedimentary rocks, both these rock types being cut by a suite of dolerite, trachyte and rhyolite dikes. The dikes range in thickness up to 2.3 m; c. 200 dolerite dikes have been identified and 32 of intermediate composition (Edmunds et al. 1979).

Geochronology

Mineralization age:Paleocene : 58.7 ± 1.6 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.
