Nigeria Gold Prospectivity Map (Phase 1)

Overview

This dataset contains the Phase 1 heuristic gold prospectivity map for Nigeria, generated using the NORA (Nigeria Open Resource Atlas) environmental and gravity layers.

Methodology

The score is calculated based on a weighted heuristic of:

—Gravity Anomalies (30%): Identifying density variations linked to mineralized zones.
—Terrain Roughness (20%) & Slope (15%): Geomorphological indicators of structural controls.
—Elevation (15%) & Aspect (5%): Hydrological and exposure factors.
—Terrain Context (15%): Combined index of local geomorphology.

Files

—nigeria_gold_prospectivity_phase1.tif: GeoTIFF raster at 0.02-degree resolution (approx. 2km grid).

Usage

The scores range from 0 to 100, where 100 represents high theoretical prospectivity based on the input layers.
