In the Californiagold rushof the 1800s , the metalpyritewas known as “ fool ’s gold ” because it mimic the real thing , dupingentrepreneurs into think they had struck it rich .
agree to science , they may have been on to something after all — iron pyrite does turn back real gold , though it ’s more of a pallid joke courtesy of nature than anything that would have benefited them financially .
In a newfangled research articlepublishedinGeology , researchers examining iron pyrite with an atom investigation ground tiny little specks of gold invisible to the raw eye embed in the alloy . The gold is obscure in “ nanoscale crystal defects , ” which are visible only with special atom visualisation tools .
The work was conducted by Curtin University , the University of Western Australia , and the China University of Geoscience . Lead investigator Dr. Denis Fougerousesaidin a press discharge that the “ unseeable ” Au had never been recognize previously , though pyrite was known to bear Au nanoparticles . Pyrite - gold alloys also exist .
So how did the atomic number 79 wind up there in the first position ? Researchers conceive that as the pyrite develop , it was dependent to imperfections in its complex body part that would allow for trace of gold to become plant inside . So , technically speaking , anyone trash for gold who dismissed pyrite could have been holding some Au in their paw .
" The more deformed the crystallization is , the more gold there is locked up in defect , " Fougerouse said . “ The gold is host in nanoscale defect calleddislocations — one hundred thousand times smaller than the width of a human tomentum — so a special technique call atom probe tomography is need to discover it . ”
unluckily , there ’s no easy room to call back it . Fougerouse said that one method acting may involve an descent unconscious process have sex as selective leaching , which would dissolve the amber using the dislocations as fluid pathway . That ’s heady stuff for the 21st hundred , let alone the nineteenth century . iron pyrite may contain gold , but it still would n’t have done anyone in the aureate hurry much honest .
