Mindat Locality ID:

Long-form identifier:

GUID (UUID V4):

A late intrusive phase associated with the Brandberg anorogenic granite intrusion. Early Cretaceous fenitized peralkaline arfvedsonite-aegirine granite and associated agpaitic pegmatites. Located in the SW periphery of the Brandberg Complex.

The Amis complex is a ~4 × 2 km large, late-stage intrusive center located at the periphery of the Brandberg granite pluton that intruded concordantly into volcanic-sedimentary country rocks and early-formed granites of the main pluton. A fine- grained arfvedsonite granite that is also known as “brandbergite” intrudes the Brandberg main granites as subvertical dikes, providing stratigraphical evidence that the Amis complex postdates the main intrusion.
