Conway granite
Conway granite is a typically pink (or
particle size (with portions of the rock fine-grained or porphyritic).[1]
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.[2]
Geologist
White Mountains, such as Franconia Notch, Crawford Notch, the center of the Pemigewasset Wilderness, and the Saco River valley. Other exposures of the formation include the Belknap Mountains south of Lake Winnipesaukee.[5]
