The Gaudeanmus area lies within the southern Central Zone of the NE-trending branch of the Damara orogen. Petrographical and geochemical characteristics of alaskite as well as its petrogenesis and geological features in the Gaudeanmus area of Namiba were studied in this paper. The alaskite sample displays variable mineral and chemical composition. The alaskites in this area range in composition from tonalite to alkali-feldspar granite. The alaskites have been divided into six distinct types based wholly on observable field characteristics of color, grain size, texture, radiometric measurements by scintillometer and macro-scale mineralogy. Cross-cutting and structural relationships were used to create a chronological sequence from type A which is the oldest to type F which is the youngest. Geochemical analyses show that the alaskites contain high silica and alkali, with relatively low manganese, magnesium, sodium, phosphor and calcium. The alaskites show peraluminous to metaluminous characteristics and belong to high-K calc-alkaline to shoshonite series. Major elements of different types of alaskites do not show characteristics of homogeneous evolution, so they are inferred to be products of different stages of orogeny.
