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
Granite spiny lizard Granite spiny lizard The granite spiny lizard (Sceloporus orcutti) is a species of phrynosomatid lizard. The epithet, "orcutti", honors American naturalist Charles Russell Orcutt (1864–1929), who collected the type specimen in San Diego County, California. It is endemic to southern California in the United States and Baja California in Mexico. The granite spiny lizard is snout-to-vent length. Maximum total length including the tail is . Its dorsal scales are strongly keeled and pointed on its body and tail. It has a wide purple mid-dorsal stripe. The males of the species have yellow-green and blue-centered scales on the body; juveniles and
