Putnisite is a mineral composed of strontium calcium chromium sulphur carbon oxygen and hydrogen. It was discovered on the Polar Bear peninsula in Western Australia in 2014 during mining activity. The mineral was named after mineralogists Andrew and Christine Putnis. Putnisite has unique chemical and structural properties and does not appear to be related to any of the existing mineralogical families. Putnisite occurs as small (< 0.5 mm) cube-like crystals in volcanic rock.
