Economic Potentials of Clay Deposit in Akanu Ibiam Federal Polytechnic Unwana, Afikpo North Ebonyi State
Different studies and investigations have proved that Unwana town is rich in argillaceous rocks of considerable economic importance. The clays and shales range in age from the cretaceous of tertiary in the geological time frame. The clays deposited during the cretaceous period are richer in qualities. The study shows that Unwana clays are high in refractory (SIO2  and AI1 C3  ) with corresponding low  fluxes (Mgo, Cao, K2O Na2O Tio2) which makes them good materials for making of low duty refractories, vitrifying and non vitrifying structural clay wares and finished ceramic products. Also the high cost and frequent shortage of cements and the occurrence of large deposit of clay minerals within Alkanu ibiam federal polytechnic and the need to have varied construction material necessities the establishment of brick factories too.
