A Comparison of Geospatial Interpolation Techniques for Gold Anomalies in Wassa - Amenfi District, Southwest Ghana

Emmanuel Ayitey, Christiana Nyarko, Henry Otoo, Micheal Affam & Peter Kwesi Nyarko · Asian Journal of Geological Research · 2022

In spatial interpolation, the Inverse-Distance Weight (IDW) and Kriging methods are two of the most widely used deterministic and geostatistical models. In deterministic techniques, interpolation is performed using mathematical functions, whereas geostatistics uses statistical an...

Extreme Value Theory Modeling of Geochemical Anomalies: Block Maxima Approach

Emmanuel Ayitey, Christiana C. Nyarko, Henry Otoo & Micheal Affam · Asian Journal of Probability and Statistics · 2022

Mineral shortages can be avoided if the mineral industry accurately predicts mineral deposits, which is critical given the importance of minerals in Ghana's economy. The goal of this dissertation was to use the block maxima (BM) approach of Extreme Value Theory (EVT) to accuratel...
