Specifications include, but are not limited to: The State of Alaska Geologic Materials Center (GMC) in Anchorage seeks the purchase of a Hyperspectral Scanning Instrument (HSI) for analysis and digital preservation of significant portions of its rock sample holdings. The HSI should be logistically optimized to handle tens-ofthousands of single to multi-row cores in plastic, cardboard, or wooden boxes. The HSI will generate high-resolution RGB sample images, high-density mineralogical spectral data cubes, and potentially 3D laser sample profile datasets. All data storage will be locally hosted on GMC data clusters. All quality assurance and pre- and post-processing, including preliminary mineral and alteration maps, will occur in-house at the GMC. The HSI will operate from a climate-controlled warehouse (see Attachment 5). More than 60 feet of roller and ball bearing tables will front load the scanner and handle pre- and post-scan core boxes that are stored on nearby warehouse racks on pallets. A forklift and shrink-wrap machine will assist core box management. An adjacent HEPA filter vacuum system and other tools will clean the core before scanning. Water systems are not available for cleaning. Network and electrical utilities will drop from above to the instrument. The ideal staffing is a combination of one geologist and two natural resource technicians. Contiguous core scanning of the mineral and energy core collections should take less than two years. HSI examinations of washed drill cuttings and fieldbased hand samples will follow the core scanning activity.
