If we ever get proof of past life on Mars, it’ll come in the form of biosignatures, fingerprints that could only have been left by living organisms. We’re a long way from finding that smoking gun evidence, but an analysis of silica minerals discovered by NASA’s Spirit rover pushes us one step closer. Because of their…
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.
A new study by Australian geologists has shown that over 80% the world's commercial gold deposits were generated in a flash process, the result of depressurizing earthquakes that rapidly converted mineral-rich fluids into precious veins of gold.
The most recently discovered mineral is krotite, which was recently discovered in a meteorite fragment. Krotite has never been seen in nature before now, and yet its origins reach right back to the birth of the solar system.
