NASA’s Perseverance rover has uncovered high-purity quartz crystals on Mars, a discovery that could reshape the search for ancient life on the Red Planet. The crystals, along with other minerals such ...

Ranging in size from large chunks to tiny beads ... Fractured Crystals These crystals, often called "shocked quartz," show a distinctive pattern of fracturing caused by high-energy impacts ...

THE extensive use of quartz in piezoelectric oscillators has stimulated the production of synthetic quartz crystals. Spezia 1 in 1906 grew quartz at a temperature somewhat below 300° C.

The magic of crystal formation had already been done by natural processes; all that was needed was a little slicing and dicing. As it turns out, though, quartz is so immensely useful for a ...
