Located in the South-West Pacific, at northern extremity of mostly submerged Zealandia continent, New Caledonian Exclusive Economic Zone (EEZ) covers 1,470,000 km² and includes basins, ridges seamounts where abundant ferromanganese crusts have been observed. Several investigations conducted since 1970s on nature composition from Caledonia’s ridges, but none covered entire EEZ. We present data 1...

Carbonate-substituted hydroxylapatite is the inorganic component in bone. The nanometer size of bone crystallites and their interweaving with subequal volumes of collagen fibrils make the chemical analysis of the bone mineral extremely difficult. The few chemical analyses that are available commonly were made on ashed bone, which, in addition to mineral, also includes chemical residues of colla...

30 Abstract—The blessings of hyperspectral remote sensing are manifold and it has enabled researchers to locate, map and identify different materials on the surface of Earth. Hyperspectral remote sensing play a key role in mineral mapping activities and it can be a much powerful and cost effective tool for mineral development activities in a developing country like Pakistan where there are rich...
