Latitude & Longitude (decimal): -21.1513888889, 14.3055555556
Age:132.14 ± 0.40 to 131.90 ± 0.58 Ma
Geologic Time:Early Cretaceous
Dating method:The most recent dates (#40#Ar-#39#Ar) for the Awahab quartz latite units are 132·14 ± 0·40 and 131·90 ± 0·58 Ma for the Gobobseb quartz latite Units I and II, and 132·03 ± 0·40 Ma for the Springbok quartz latite, the ages overlapping within experimenta
Reference for age:https://web.archive.org/web/20070317033342/http://www.oxfordjournals.org/our_journals/petroj/online/Volume_39/Issue_02/html/egb091_gml.html


The Goboboseb Mountains cover an area of 1100 km² and are assigned to the Awahab Formation consisting of interbedded basalts & quartz latites that form part of the 132-135 million-year-old Etendeka Group. Strong evidence suggests the source of the Gobobobseb volcanic rocks comes from the Messum Complex. The highest peak of these mountains is the Tafelkop.

NOTE: The actual mountains where the famous amethyst and quartz crystals (sometimes in sceptre form) is mined are the Goboboseb Mountains (basalts of volcanic origin), located approximately 35 km west of the Brandberg (specimen labels often give the locality as Brandberg). The name "Brandberg crystal" or "Brandberg quartz" originates from the fact that the Brandberg (granite massif!) is a world wide known name and it is easier to explain than the Goboboseb range.
