Application of GOCE Satellite Gravimetric Data For Mineral Exploration

Gravity is directly proportional to density thereby making possible the use of measurable gravity in mapping variations earth’s interior. The as a means mineral exploration cost-effective for wider area coverage. GOCE data, collected by ESA’s satellite at 255km altitude and 10km intervals leading acquisition multiple points over globe made application gravimetry exploration. disturbance data sourced from BGI- was corrected with WGM2012 corrections computed using EGM2008 geoid ETOPO1 models, reference Somigliana formula. disturbances were mapped Zambia Surfer Q-GIS, 600 control known occurrences plotted together other surface features like roads, rivers, railways, etc. By relating varying triple integral principle, cautious analysis led geological classification which essentially involved predominant across different parts Zambia. During ground truthing, it observed that results within particular interest on classified map, those obtained four (4) metal detectors well another remote sensing method tallied. used GR-100MINI, AKS, AKS plus 3D, Garrett Ace 400, each its own characteristics. From map outputs, showed can be delineation terrain types. types output matched existing maps also offered sub-terrain
