Editing Peridot (section)

=== Surface property ===
Oxidation of peridot does not occur at natural surface temperature and pressure but begins to occur slowly at {{convert|600|C|K|sigfig=2}} with rates increasing with temperature.<ref>{{cite journal |last1=Knafelc |first1=Joseph |last2=Filiberto |first2=Justin |last3=Ferré |first3=Eric C. |last4=Conder |first4=James A. |last5=Costello |first5=Lacey |last6=Crandall |first6=Jake R. |last7=Dyar |first7=M.
