Rock Quarries In Nigeria

Evaluation of some engineering properties of granitic rock types were carried out in selected quarries in Ekiti and Ondo states, Nigeria. The Rock Quality Designations RQD); Uniaxial Compressive Strength (UCS); and Aggregate Crushing Value (ACV) of the rocks were determined both in the laboratory and on the field using international standard procedures.

Environmental degradation due to abandoned mines and quarries in South-western Nigeria was assessed on the basis of measured physical parameters namely acidity and conductivity and concentrations of heavy metals and other trace elements in collected water and soil samples vis-à-vis minerals mined and site by site basis.
