Conway granite Conway granite Conway granite is a typically pink mineral-rich igneous (or mesoperthitic) biotite granite. It is amphibole-free and of coarse particle size (with portions of the rock fine-grained or porphyritic). Conway granite has a relatively high concentration of thorium, at about 56 (±6) PPM; this amount is not enough to make the granite dangerously radioactive, but it is sufficient to make the rock a low-grade (almost certainly not economic, at least in the early years) source of thorium for a thorium fuel cycle. Geologist Edward Hitchcock named the granite in 1877 after the town of Conway, New Hampshire, which is

On the western side of Kokerbin Rock is a historic stone well and an old school site, remainders of early European settlement. <mapframe text="Kokerbin Rock is located within the Kokerbin Nature Reserve" width=300 height=300 zoom=15 latitude=-31.88772 longitude=117.70484>{ "type": "ExternalData", "service": "geoshape", "ids": "Q16893567", }</mapframe> Kokerbin Rock Kokerbin Rock, also known as Kokerbin Hill, is a granite rock formation located within the Kokerbin Nature Reserve in the Wheatbelt region of Western Australia.
