| | EUHEDRAL CRYSTALS OF FERROAN PLATINUM, COOPERITE AND PALLADIAN ANTIMONIDE FROM THE DARYA PLACER, ALDAN SHIELD, RUSSIA (Site not responding. Last check: 2007-09-18) |
 | | Another crystal, characterized by the formula (Pd,Cu)20(Sb,As,Sn)7, has micron-sized (2-5 µm) inclusions of sperrylite and deformation textures clearly visible in polished section. |
 | | Previous studies of the Darya heavy mineral concentrate reveal the presence of low-Ir (Ir <0.5 wt.%) Pt-Fe alloy, crystals of sperrylite and cooperite, isomertieite, and very rare Ir-Os-Ru alloy. |
 | | Euhedral crystals of ferroan platinum alloy (up to 1.5 cm large) were only known from the Kondyor deposit so far. |
