Abstract
The Gongola arm of the Upper Banue Trough, Northeastern Nigeria is predominantly covered by the outcrops of Limestone-bearing rocks in form of Sandstone with intercalation of carbonate clay, Shale, Basaltic, Felsphatic and Migmatite rocks at subpixel dimension. In this work, subpixel classification algorithm was used to classify the data acquired from landsat 7 Enhance Thematic Mapper (ETM+) satellite system with the aim of producing fractional distribution image for three most economically important solid minerals of the area: Limestone-bearing Sanstone, Basalt and Migmatitic Schist/Gneiss. Linear Spectral Unmixing (LSU) algorithm was used to produce fractional distribution image depicting the abundance of the three mineral resources within a 100Km2 portion of the area. The results show that the minerals occur at different proportions all over the area. The fractional map could therefore serve as a guide to the ongoing reconnaissance for the economic potentiality of the formation. Key Words- Linear Spectral Unmixing, Upper Benue Trough, Gongola arm
