Abstract: The natural process of compaction serves as the main diagenesis process which results in reduced porosity and formation of pore systems and improved mechanical properties of sedimentary basins. The process has been identified but scientists have not yet found the particular textural features which control natural geological environment compaction efficiency. The research explores how the compaction characteristics of loose sandy sediments get controlled through the particle size distribution (PSD) and sorting characteristics which develop during their deposition process. The researchers performed standard......

Abstract: The study applies high-resolution aeroradiometric data to map hydrothermal alteration zones for gold exploration and delineated surface geology in parts of the northwest Nigeria schist belts. The work uses eight NGSA radiometric sheets covering parts of Zamfara State and adjoining parts of Sokoto and Kebbi. Processing and map production were completed in Oasis Montaj software, followed by GIS-based interpretation and integration. Individual radioelement maps for %K, eTh, and eU were generated, then three hydrothermal alteration indicators were computed: K/Th ratio, F parameter, and potassium deviation (Kd). A fuzzy logic weighted overlay combined......
Keywords: aeroradiometric mapping, hydrothermal alteration, gold mineralisation, fuzzy logic weighted overlay and schist belts.

Abstract: Wagusu magnetic data set was analyzed to delineate crustal signatures that could favor exploration of economic minerals. Depths and edges for litho-structural anomalies were detected by using high resolution methods of Analytic Signal, Tilt angle Derivative and Power spectral analysis, in Oasis Montaj software. Magnetic anomaly distribution in the area ranged between 931.1 nT and 1020.2 nT. The RTP maps revealed variation of causative structures striking in North East-SouthWest direction. The overlain analytic signal revealed maximum signal values over the anomalies covering an estimated area of 4,000,000 m2.......
