Volcanic field that extends southwards to the border with Yemen and is probably a northerly continuation of the Yemen Volcanic Series. The field includes at least 35 basalt flows, with a total thickness of up to 580m, together with the basaltic plugs, necks and dikes and peralkaline trachyte intrusions (du Bray et al. 1991).

Geochronology

Mineralization age: Cenozoic : 30.1 ± 1.0 Ma to 22.5 ± 0.7 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.
