Cretaceous Geology; Age-determination; Economic Geology; Sokoto Basin; Northwestern Nigeria.

In this present study, the geology and economic aspect of lithological units of Sokoto Basin, sheet 4 South West Sokoto, part of Nigerian Sedimentary Basins were studied. It is bounded by latitudes N 13° 36′ 30″- N 13° 40′ 45″ and longitudes E 05° 38′ 00″- E 05° 40′ 44″to gently undulating plain which was mapped on the scale of 1:25,000. The methodology adopted was mainly primary data which involved reconnaissance survey and actual or full field survey. The economic deposits include clays/ shale, lateritic ironstones, limestone, phosphate and gypsum, which are mined by the local artisanal miners.
