The mineral 'Putnisite' , described by a visiting research fellow at the University of Adelaide in Mineralogical Magazine, was found in a surface outcrop at Lake Cowan, north of Norseman in Western Australia. The new mineral occurs as tiny crystals, no more than 0.5 mm in diameter and is found on a volcanic rock. It appears as dark pink spots on dark green and white rock which, under the microscope, appears as square, cube-like crystals. It combines the elements strontium, calcium, chromium, sulphur, carbon, oxygen and hydrogen — a very unusual combination.
It has yet to be determined if the new mineral will have any practical use, researchers said. Putnisite has been named for Australian mineralogists Andrew and Christine Putnis.
