IRUG filename: IMP00380 | Data type: Infrared | IRUG material class: Minerals and pigments (MP) |
Sample type: Reference material | Common name(s): Ikaite, possibly | Chemical/botanical name(s): Hydrated normal carbonate (class), nesquehonite (mineral group) |
Source location 1: Barrow, Alaska, US | Sample source 2: The Natural History Museum, National Museums of Scotland | Source location 2: Cromwell Road, London, SW7 5BD, UK, Edinburgh, UK |
Sample identifier 2: NHM unregistered | Color: Brown | Other: Ikaite is unstable at room temperature and is stowed below 0 degrees C, this specimen may be partially decomposed to calcite plus water, spectrum was checked by repeating as a mull which gave an identical result |
