A Strange New Mineral Has Been Discovered in Australia

It's purple, translucent and goes by "putnisite." Discovered in Western Australia, putnisite contains the unusual elemental combination of strontium, calcium, chromium, sulphur, carbon, oxygen and hydrogen and is notable for its dissimilarity from other, known families of minerals.

PopSci's Douglas Main has the details:


While dozens of new minerals are discovered each year, it is rare to find one that is unrelated to already-known substances. "Most minerals belong to a family or small group of related minerals, or if they aren't related to other minerals they often are to a synthetic compound—but putnisite is completely unique and unrelated to anything," said Peter Elliott, co-author of a study describing the new substance and a researcher at the South Australian Museum and the University of Adelaide, in a statement. "Nature seems to be far cleverer at dreaming up new chemicals than any researcher in a laboratory."
