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 rat...

Discrimination of granitoids bearing iron and corundum mineral deposits in the southeastern part of Banyo (Adamawa region of Cameroon) using Landsat 8 OLI data and provides essential information’s for exploration. Field data and remote sensing traditional mapping techniques including false color composites (FCCs), principal component analysis (PCA)...

The mylonitic band of Rey Bouba Greenstone Belt (RBGB), oriented NE-SW that straddles between the Neoproterozoic batholite of the northern domain to the NW and the Adamawa-Yadé Paleoproterozoic domain to the SE, is a Neoproterozoic back-arc basin made of deformed volcanosedimentary rocks. A tectonic and microtectonic study of this basin was carried...

Bound to the north by the Sahara and to the south by the Sudanian savannah, watersheds in the African Sahelian belt supply food and water to an estimated 135 million people. Being one of the Earth's most vulnerable zones to climate change impacts, the Sahel covers a 3.1 million km2 corridor from the Atlantic Ocean in the west to the Red Sea in the...

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 ava...

Hangloa granitoids form part of the wide range calc-alkaline Pan-African granitic suites within the Adamawa Yade Domain (AYD) in Cameroon. There are several reports on metaluminous granitoids within this domain. The peraluminous suite has been locally reported and their petrogenesis is not fully understood. Petrography and whole-rock geochemistry w...

Pawara area is a mining district in the eastern region of Cameroon. Mining in the area is generally artisanal and semi-mechanized, practiced by the local miners and immigrants from neighboring African countries and China. The lack of strict regulations and control of mining activities permits the miners to use illegal substances, especially Hg in g...

Somie-Ntem area of the Tikar plain belongs to the western Cameroon Domain. The lithology of the plain has been characterized, and the mineral potential is still unclear despite previous reports on Sn deposit within one of the magmatic complexes. Our results show two groups of granitic rocks displaying oxidized and reduced character; (1) mesocratic...

The purpose of this research paper is to delineate several hydrothermal mineral deposits in Banyo area using remotely sensed data and techniques. To achieve the best results in this research, false color composite, PCA, and BR techniques are used. To clearly distinguish the lithologies of SE Banyo area, Landsat 7 ETM+ image processing algorithms su...

Remote sensing is a robust and useful tool for providing high‐resolution image data and enabling reliable geological mapping during the initial stage of mineral exploration. One of its main applications is the extraction of lineaments and to locate alteration areas to target gold exploration. It has been long used in the Pan‐African belt of Cameroo...

La zone du complexe Binational des parcs nationaux transfrontaliers de Sena Oura et de Bouba Ndjida avec leurs zones périphériques (zones agro-pastorales et zones d'intérêt cynégétique) fait l'objet d'une pression de plus en plus forte du fait de l'accroissement conjugué des populations humaines et de l'élevage bovin. Les espaces encore plus ou moi...

The Bindiba gold district study in the East Cameroon region was done using a combination of Landsat 8 ETM image processing techniques, SRTM imagery and fieldwork. The various digital processing methods of treatment applied such as color compositions and component analysis showed lithological differentiation of the different formations of the stu...

The use of phosphate rocks has become agronomical and economically more beneficial compared to chemical fertilizers. In this study, the fertilizing effect of vivianite (a phosphorus rich mineral) from Hangloa on the growth and yield of the bean plant ‘‘Phaseolus vulgaris’’ on oxisoils from Ngaoundere is assessed. To this end, field investigations a...
