[edit] Summary
Photo by user:Rolinator. Taken August 2006. This photo shows typical A3 facies bladed olivine spinifex, Widgiemooltha Komatiite, Widgiemooltha Dome, Western Australia. The sample is from drill core from drillhole WDD18, at approximately 139m downhole. The olivine crystals form sheafs or booklets of plated crystals within glass, which has since been metamorphosed to a chlorite-actinolite-serpentine-magnetite assemblage and sulfidated from magnetite to pyrite. It is rare to see such perfectly preseved spinifex textures within serpentinised ultramafic rocks.
NB: Text on the drill core "UKAH0" is local logging code, U = Ultramafic, K = spinifex textured, A = amphibole, H = chlorite, 0 = undefined. Rolinator 03:34, 21 August 2006 (UTC)
