Granite-related mineralization.
Cligga Head granite is intruded in Devonian metasediments.
The granite is cut by greisens-bordered NE vein-system.
The greisens are cored by Sn-W-As-quartz veins.
Sulfide mineralization occurs in fractures cross-cutting Sn-W-As-quartz veins.
The granite is rimmed by a tourmalinite alteration aureole.
Hydrothermal activity : 350-400°C, 0.7 (boiling)-1.7 kb.
Na-K-Fe-Ca chloride brines rich in B, F, SO4 (degassing of magmatic volatiles).

This locality includes
- Cligga Mine, which is listed as a sub-locality
- the exposure of the greisen-sheet vein stockworks (another SSSI, so keep hammers in bags!), located just below the 1940s mine works on the top of the cliff, and
- the beach, with numerous vein outcrops and scattered material from cliff falls.

The beach at the entrance to the mine yields arsenopyrite, cassiterite, small scorodites and wolframite without having to look too hard. More minerals are found on the beach around the cliff past the mine entrance, which extends about 1/2 mile farther south. Around the cliff at the southern end of the beach is Hanover Cove (see separate entry), which can be accessed only at lowest tide.

Geochronology

Mineralization age: Cisuralian : 275 ± 6 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.
