K-AR AGES, MINERALOGY, MAJOR AND TRACE ELEMENT GEOCHEMISTRY OF THE TERTIARY-QUATERNARY LAVAS FROM THE NDU VOLCANIC RIDGE N.W. CAMEROON

The Ndu Volcanic Ridge occupies the central position amongst the continental sector volcanoes of the Cameroon Volcanic Line. K-Ar age determination coupled with field observations show that there were three episodes of volcanic manifestation: 31-28 Ma; 23-21 Ma and African Journal of Science and Technology Vol.5(1) 2004: 47-56
