Ozernaya Mount, Dzheltul'skii massif, Kureika river, Taymyrskiy Autonomous Okrug, Eastern-Siberian Region, Russia Cubic graphite pseudomorph after an unknown precursor (some time speculated to be diamond). Exposed from native iron-filled voids in basalt by dissolving the iron in aqua regia. The cube is approximately 0.2 mm across. Mindat.org Photo of the Day - 26th Oct 2008 |
