Geologic Time:
Dating method:
The most recent dates (40Ar-39Ar) 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 experim
The Goboboseb mountains cover an area of approximately 1,100 km² and are assigned to the Awahab formation, which consists of interbedded basalts and quartz latites belonging to the 132–135 million-year-old Etendeka group. Strong evidence indicates that the volcanic rocks of the Goboboseb area were sourced from the Messum complex. The highest peak of the range is Tafelkop.
Important mineral collecting note: Although amethyst specimens have been found within the Brandberg complex (where digging is prohibited, as it is a protected World Heritage Site), the majority of the material circulating on the market actually originates from the Goboboseb mountains. However, dealers often label these specimens as "Brandberg", as the complex is a better-known and more widely recognized locality (see Cairncross, B. & Bahmann, U., 2006 for further details).
