The Rocklea Dome 3D Mineral Mapping Test Data Set

Abstract. The integration of surface and subsurface geoscience data is critical for efficient effective mineral exploration mining. Publicly accessible sets to evaluate the various analytical tools their effectiveness characterisation assemblages lithologies or discrimination ore from waste are however scarce. open-access Rocklea Dome 3D Mineral Mapping Test Data Set (Laukamp, 2020; https://doi.org/10.25919/5ed83bf55be6a) provides an opportunity evaluating proximal remote sensing data, validated calibrated by independent geochemical mineralogical analyses, channel iron deposits (CIDs) through cover. We present hyperspectral airborne, surface, drill core reflectance spectra collected in visible–near-infrared shortwave infrared wavelength ranges (VNIR–SWIR; 350 2500 nm), as well whole-rock geochemistry obtained means X-ray fluorescence analysis loss-on-ignition measurements samples. with frame previously published case studies demonstrated that about 30 % holes were sunk into barren ground could have been better use, located elsewhere, if airborne imagery had consulted hole planning. mapping transported Tertiary detritals (i.e. potential hosts resources) versus weathered situ Archaean bedrock ground) has significant implications other areas where “cover” regolith and/or sediments covering hosting deposits) hinders exploration. Hyperspectral represents a cost-effective method landform required planning drilling programmes. In area, vegetation unmixing methods applied integrated resulted seamless zones base CID – concept can be deposit studies. Furthermore, associated, calibration allowed quantification oxide phases associated mineralogy data. Using set, novel geostatistical clustering body domaining introduced scientific rigour traditionally subjective procedure, resulting reproducible objective domains mining process. Beyond studies, develop new advanced resource applications aid white mica chlorite abundance maps derived hyperspectral, presented here first time, highlight additional geological help newly launched hyper- multispectral spaceborne systems
