7228 JL1036 Siderite, Calcite, Barite, Quartz, Martins Well, South Flinders Ranges, Flinders Ranges, South Australia

Barry Porter “typical of the Reaphook Hill geodes, a lot dug in the 80s, had to walk a few ks from the Scholzite deposit until we found a 4wd track in. Very hard slaty rock to split, geodes from 1 cm to 12cm the biggest I saw. Occurred in layers, sometimes a lot of nothing and then a layer will have geodes every few 10s of cm.”. Purchased for $2 from Barry Porter in 1992.
