Fuzzy-logic technique for gold mineralization prospecting using Landsat 9 OLI processing and fieldwork data in the Bibemi goldfield, north Cameroon.

Identifying potential hydrothermal alteration areas is indeed an essential method for mineral exploration. In this research, we developed an algorithm for the delineation of alteration mineral deposits related to gold mineralization in the Bibemi region using set of criteria derived from Landsat 9 OLI data using false colour composites, band ratios, principal component analysis, spectral angle mapper, and fuzzy-logic overlay methods. The methods used showed iron-oxides, ferrous, and hydroxyl-bearing and carbonate mineral properties related to gold mineralization.

Assessment of water availability for agricultural activities in the savannah Plateau of Adamawa-Cameroon.

The availability of water for agricultural use in the savannah plateau of Adamawa, Cameroon, is addressed in this paper. Specific field tests coupled with climatic data analysis have helped to characterize the hydrological and hydrogeological conditions of water resources in a small catchment. An agricultural suitability map, based on the water availability during the dry season, is produced.
