About the Cover

Combined Geophysical surveys involving ground magnetic, Very Low Frequency Electromagnetic (VLF-EM), Vertical Electrical Sounding (VES) and Horizontal Profiling (HP) (VES&HP), and Induced Polarization (IP) were carried out at the gold mining site of Iperindo, Southwestern Nigeria. This is aimed at delineating geologic structure and its relation to mode of mineral occurrence and depth to mineralised body. This demonstrates the reliability and effectiveness of combined geophysical surveys in mineral exploration. Interpreted profiles of ground magnetic data revealed fractures, veins, and lithological contact in the study area. Depth estimation of delineated geological structure using Peter’s half slope method shows the depth vary between 50 m and 500 m. VLF-EM results revealed shallow linear geological features occurring at depth range of 40 - 200 m. The linear features approximately trend NE-SW, W-E, and NW-SE directions. Interpretation of VES/HP and IP results showed variations in resistivity and chargeability values, respectively. Delineated geologic structures from VES/HP interpreted 2-D section correspond to zone of high chargeability from IP interpreted 2-D section.

An assessment of forest degradation in Taraba Central Zone, Nigeria

Oruonye ED, Bashir Babanyaya Mohammed, Anger RT, Ahmed YM

This study assesses forest degradation in the Taraba Central Senatorial District of Nigeria over a 30-year period, utilizing Normalized Difference Vegetation Index (NDVI) data to analyze changes in vegetation cover. The results reveal a significant decline in areas of dense vegetation, from 2,560.28 km² in 1993 to 1,972.29 km² in 2003
