The Goanikontes area lies within the Central Zone of the northwest -trending branch of the Damara Orogen. The cover succession of the area is in tectonic contact with older pre-Damaran basement rocks. Sheeted granitoid intrusions are extremely well exposed and these leucogranite sheets, locally termed alaskites, intrude both basement and the Damaran cover sequence. The area is characterised by a northeast-plunging anticline which is truncated by a high strain zone to the east. Red and grey granite emplacement was followed by sheeted leucogranite intrusions which are preferentially located within the high strain zone. These sheets can be classified into six different types and ages on the basis of field characteristics. Major element data on the leucogranites, recalculated into cation normative compositions, show a compositional range from granodiorite to alkali feldspar granite, whereas modal proportions indicate a range from monzogranite to alkali feldspar granite. There is, however, an overall compositional trend, with increasing content of alkali feldspar with younger age. Primary uranium mineralisation is restricted to a single leucogranite type and is confined to the upper Khan and Rössing Formations within the high strain zone. Secondary hydrothermal mineralisation is widespread and is not restricted to either the high strain zone or any lithological unit.
