Unravelling the Deformation of Paleoproterozoic Marbles and Zn-Pb Ore Bodies by Combining 3D-Photogeology and Hyperspectral Data (Black Angel Mine, Central West Greenland)

The Black Angel Zn-Pb ore deposit is hosted in folded Paleoproterozoic marbles of the Mârmorilik Formation. It exposed southern part steep and inaccessible alpine terrain Rinkian Orogen, central West Greenland. Drill-core data integrated with 3D-photogeology hyperspectral imagery rock face allow us to identify stratigraphic units extract structural information that contains geological setting this important deposit. stratigraphy distinguishes chemical/mineralogical contrast within lithologies dominated by minerals are difficult distinguish naked eye, a similar color dolomitic scapolite-rich calcitic, graphite-rich marbles. These results strengthen our understanding deformation style subdivision between evaporite-carbonate platform facies carbonate slope facies. Ore formation appears have been mainly controlled stratigraphy, mineralizing fluids accumulating permeable underneath shales as cap rock. Later, folding shearing were responsible for remobilization improvement grades along axial planes shear folds. contact calcitic probably represents direct marker, recognizable drill-cores, be addressed further 3D-modeling exploration area.
