Located 60 km north of Hentiesbaai, a headland mostly famous for its seal colony.
Much of the Cape Cross Peninsula is occupied by Karoo lavas and intrusive rocks or obscured by recent deposits, including evaporites, but Gevers (1933) described a small area of alkaline rocks intruding the Karoo that is probably part of a large complex extending beneath the sea.

Geochronology

Mineralization age: Early/Lower Cretaceous : 140.2 ± 1.0 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.
