Department of Geology, University of Ibadan Nigeria gbengaokunlola yahoo. Amphibole and quartz schist which occur in association with migmatite gneiss, granitic gneiss and Pan African Older Granite bodies around Ibadan area, southwestern Nigeria, were studied with a view to elucidate their compositional characteristics and their evolution. Mineralogical determinations from optical studies show a high proportion of granular quartz and accessory muscovite in the quartz schist. The amphibole schist on the other hand comprises mainly dark colored bands of hornblende with subordinate tremolite, chlorite and minor amounts of plagioclase and quartz. Chemical analysis of the samples obtained by Inductively Coupled Plasma Mass Spectrometry ICPMS instrumentation method, involving major and trace elements reveal the silicieous nature of the quartz schist and and the amphibole. In addition, variation plots using Na2O, K2O suggests arenaceous sedimentary ancestry for the quartz schist and an igneous ancestry most probably mafic extrusive volcanics for the amphibole schist. Provenance indicators, such as Ba, in the quartz schists suggest derivation of this sedimentary protolith from the weathering of largely granitic rocks.
The University of Ibadan UI is the oldest degree awarding institution in Nigeria ,   and is located five miles 8 kilometres from the centre of the major city of Ibadan in Western Nigeria. It is popularly known as Unibadan or UI. A thirteenth, Economics, Environmental Design and Management, is proposed.
