(iv) Older granites, which comprise rocks varying in composition from granodiorites to true

granite and potassic sysnite.

(v) The unmetamorphosed dolerite dyke is believed to be the youngest.

These rocks are believed to have been emplaced during the Pan-African Orogeny and are

therefore thought to be of Pan-African age (i.e 600 ±150m.years (Ramahan, 1988, Odeyemi,

1982.

SEDIMENTARY BASIN
Sedimentary basins are large depressions where sediments accumulate over millions of

years, often forming important reservoirs of natural resources such as petroleum, natural gas, and
