DELINEATION OF SOLID MINERAL STRUCTURES WITHIN PART OF NASARAWA STATE NIGERIA FROM AEROMAGNETIC AND AERORADIOMETRIC DATA
ABSTRACT Aeromagnetic data was analysed and used to delineate the structural features of the upper part of Nasarawa State of Nigeria which consists of Kuje, Keffi and Akwanga. These structural features include: lineaments, faults and folds which are channels for the accumulation of solid minerals.

Concentration maps were produced for ...
