Polished Golden Amphibolite slab GA165 chatoyance The quartz epidote axinite mineralisation

The quartz epidote axinite mineralisation was evidently caused by hydrothermal activity related to the doleritic sills which are in close proximity to the occurrence

Polished Golden Amphibolite slab GA165 chatoyance The quartz epidote axinite mineralisationGA165 A slab, polished on one side. Dimensions at widest points approximately 150 mm x 65 mm x 20 mm thick. Weighs 450 grams. The amphibolite, most likely grunerite , has now been largely altered to hematite, goethite and quartz and it displays a beautiful golden iridescence. Also called "Gold Leaf Stone". It occurs in the Pilbara region of Western Australia on Abydos Station approximately 120 km south of Port Hedland.
