Summary
[edit]DescriptionGranite quarry (Mt. Airy Pluton, 331-337 Ma, Middle Mississippian; Mt. Airy, North Carolina, USA) 1 (51360650463).jpg |
This quarry in North Carolina targets whitish-colored "Mt. Airy Granite" for the decorative stone trade. The rocks here are part of the Mt. Airy Pluton and range from monzogranites (= true granites) to granodiorites. The pluton was emplaced during the Late Paleozoic. This was a time of subduction and tectonic collision in eastern America as the Appalachian Mountains formed. Geologic unit: Mt. Airy Pluton, Middle Mississippian, 331 to 337 Ma Locality: North Carolina Granite Corporation quarry on the eastern side of the town of Mt. Airy, northeastern Surry County, northwestern North Carolina, USA (36° 30.419’ North latitude, 80° 35.375’ West longitude) |
