1. Classification of uranium deposits:
A listing of the recognized types of uranium mineralization shows nineteen determinable types out of which only six can be classified as of economic significance at present: Oligomictic quartz pebble conglomerates, sandstone types, calcretes, intra-intrusive types, hydrothermal veins, veinlike types. The different types can be genetically related to prevalent geological environments:
a. the primary uranium occurrences formed by endogenic processes (Aliyow Geelle in Bur Complex; and in Northern Crystalline Basement).
b. the secondary derived from the primary by subsequent exogenic processes (produced by processes of tropical chemical weathering such as in calcrete (the Galmudug type).
c. the tertiary occurrences are assumed to be formed by endogenic metamorphic processes.,
