The.trace.e.e.e.ts characte.istics of the.migmatitic gne.sse. (biotite.garne.and hornble.de.biotite., granulite.facie. rocks (charnockitic gne.sse.) and me.a-pe.idotite.in the.are. of Southwe.t Obudu Plate.u indicate.that the.are. e.hibits a high de.re. of ge.che.ical variability. Compatible.trace.e.e.e.ts (ni and Cr) are.comparative.y high in the.granulite.facie. rocks and me.a-pe.idotite. ni range. from 28×10-6 to 266×10-6 whilst Cr range. from 62×10-6 to 481×10-6 for the.granulite.facie. rocks (charnockitic gne.sse.), and for the.me.a-pe.idotite.ni varie. be.we.n 2045×10-6 and 2060×10-6. Incompatible.trace.e.e.e.ts show a highe. variability in the.e.rocks. The.rocks in the.are. of Southwe.t Obudu Plate.u ge.e.ally are.characte.ize. by the.high conce.trations of Ba, Ce. Sr, Rb, Ga, ni, Cr, Co, Zr, Pr and mode.ate.conce.trations of Cu, Sm and Th. The.available.data show that the.charnockitic gne.sse. are.of lowe. crustal origin. The.e.richme.t of the.me.a-pe.idotite.in compatible.trace.e.e.e.ts sugge.ts the.primitive.mantle.would be.the.source.re.ion, with slight contamination during asce.t. The.e.dive.se.origins collaborate.the.te.tonic se.ting of the.are. as shown by discrimination diagrams. The.dive.se.te.tonic se.tings range.from arc to collisional. Alkaline.to sub-alkaline.magmatism in the.are. was probably conte.porane.us with the.te.tonic e.e.ts that occurre. in the.are. during the.Prote.ozoic.
