AB  - Major and trace element variation and
discrimination diagrams from Gwagwada, Central Nigeria
show that the I-type granites of probably deep crustal
source of post collision transcurrent geological setting
was influenced by older basement materials during
emplacement based on the average A/CNK (1.54), Na<sub>2</sub>O
(3.8), lack of normative corundum as well as their high
calc-alkaline and strongly peraluminous nature. The
structural high which is evidenced by the high dips and
the strain distributions that followed the uplift and late
stage magmatism may have released ferro-potassic fluids
responsible for either leaching of barium and beryllium as
shown by the high barium content in the rocks into or
away from the basement and pegmatites. This has serious
implications for exploration efforts in the basement.
