ncat JP3295 Peisleyite, Fluorwavellite, Tom’s Quarry, Kapunda, North Mt Lofty Ranges, Mt Lofty Ranges, South Australia

Massive white peisleyite finely intergrown on a μm scale with fluorwavellite. SEM shows that ‘massive peisleyite’ consists of zones of intergrown peisleyite crystals (<3 μm in size) forming mats intermixed with zones of massive ‘wavellite’ (now considered fluorwavellite) with no distinct crystal faces. Ex Jo Price Collection. Width of view...
