Mineralpedia Details for Edoylerite
Edoylerite
Named for American mineral collector who specialized in mercury minerals, Edward H. Oyler. Edoylerlite is a rare mineral that can be found only at the type locality in the Clear Creek claim in the New Idria district in San Benito County, California, USA. There, it occurs as “a rare alteration product of cinnabar, in a mercury deposit in silicate-carbonate rock hydrothermally altered from serpentinite.” Edoylerite is photosensitive and will alter from its common canary yellow to an olive-green color after several months of exposure to the sunlight.
