Abstract

Field mapping and radiometric reconnaissance survey of Tagima and environs was carried out
with the aim of producing geologic and isorad maps of the area and identifying possible
extension of uranium mineralization southwards from the popular Mika deposit. Geologic study
shows that the area is underlain by porphyritic granite, equigranular granite, migmatite and
pegmatite. These rocks are characterized by joint and fault structures. Petrographic analysis of
the porphyritic granite, equigranular granite, migmatite and pegmatite showed that the
plagioclase, k-feldspars, biotite and quartz are the dominant minerals that constitute the rock
units. Radiometric survey shows high radiometric values in the northwestern, northeastern and
some of the southeastern parts of the area, while lower values are seen in the southern and
southwestern parts. Analyses of the results shows high potentials for radioactive minerals in
Mika and Jasori areas, while low potential for radioactive minerals in southern part of Tagima area. While Mika area has already been established to have uranium deposits, possible extension
of radioactive minerals can be traced around Jasori and Tagima with decreasing potentials
towards southern parts of the study area.
