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
Rock art of Uganda thought. Archaeologists strive to better understand cultures of the past, figuring out the meanings behind these paintings could help archaeologists to better understand what culture made them. Nyero is one of the most important rock art sites not just in Uganda but in Africa as well. It has well-preserved rock paintings that are utilized in study of rock art. The Nyero site was discovered by C.A.E Harwich in 1945. Nyero was the first rock art site to be catalogued and described in full within Uganda. Nyero itself is composed of granite, and just under 40m high. There are two areas
