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
Exfoliating granite president of the Geographic Society to receive the highest honor for geographic accomplishment; Hubbard Medal. Working his way down the Great Basin, Gilbert knew the general formation of mountains through a tectonic process, and are composed of different rock types. He observed that the mountain ranges in this area contained similarities in strata, resembling bubbles and blisters on the earth’s surface. He concluded that the mountains were once intrusive magma that had and became visible with erosion. Gilbert presented his findings in a report and contributed significantly in what future generations would know as Geomorphology. Exfoliating granite Exfoliating granite is
