“…Most especially, it is valuable for the so-called "green technologies" and the transition to more sustainable energy (Haase and Pohl, 2022). The Precambrian basement complex of Nigeria has been acknowledged for its several pegmatitic intrusions (Garba et al, 2019;Jimoh and Olatunji, 2020;Aderogbin and Okunlola, 2020;Tanko and Dzigbodi-Adjimah, 2021;Kolawole et al, 2021 andChukwu, 2022). In Nigeria, the occurrence of rare metals is broadly divided into two episodes of mineralization; the Sn -Nb mineralization associated with Mesozoic anorogenic Younger granites of central northern Nigeria, and Older (≈550 Ma) Ta -Nb -Sn -Li -Be mineralization in the pegmatites associated with the Pan-African Orogeny (Kolawole et al, 2021).…”

These mineralized pegmatites are delimited in a broad belt stretching for about 400km long from southwestern (Ijebu area) to northern Nigeria (through Wamba-Jema'a to Zuru-Gusau areas) (Abimbola and Adedibu, 2018).…”

“…The K/Rb vs Rb and K/Rb vs Cs plots for the three samples media further establishes that Egbe pegmatite is a rare metal, highly fractionated beryl type with rare metal enrichment trend of Nb>>Sn>>Ta. Kolawole et al (2021) studied the pegmatitic bodies in Bunu area within the well-known Kabba-Isanlu field in the Southwestern Nigeria. The area consists of gneiss-schist suite and intrusive suite respectively.…”

The pegmatites of Ogodo-Odobola area around Ajaokuta, Central Nigeria belong to the pegmatite belt of Central Nigeria. A detailed geological mapping of the pegmatites and host rocks was conducted with the aim of understanding their mode of occurrence and field relationship and to assess their mineralization potentials. Twelve (12) representative samples of rocks were selected for petrographic analysis. The results show that the area is underlain by migmatite-gneiss, schist, with intrusions of granite and pegmatite. The pegmatites occur in tabular form with varying widths (2 centimetres – 6 metres) and lengths (12 – 200 metres). Principal joint direction is NNE-SSW which is believed to have influenced the pegmatite emplacement. Petrography of the representative rock samples revealed an average mineralogical composition of biotite (23.90%), microcline (22.15%), hornblende (15.05%), quartz (10.65%), plagioclase (10.35%), muscovite (8.00%), myrmekite (0.20%), and opaque and accessory minerals (9.70%). The pegmatites were found to be dominated by microcline and plagioclase feldspars, and then muscovite, biotite, and accessory and opaque minerals. The pegmatite of the Ogodo-Odobola area is worth probing as the results have shown prospect for possible economic minerals.
