OK, I tried to post this last night, but it apparently didn't take. Or maybe I'm just not supposed to be able to see it.
Anyway, supposedly, there are 10 nuclei of the continents, the oldest exposed rock on the planet. I've found out a little about the one in Wyoming, and hope to visit it . . . one of these days. I also have a little information on one of the Canadian sites. Can anyone provide any information on any of the other sites?
I haven't nailed things down yet, but I'm thinking of them as a source of magic/sci fi power, or perhaps a holy site (the Wyoming site was apparently a place of worship for Native Americans).
OK, so here's my list:
Big Horn Medicine Wheel Nuclei, Medicine Mountain in the Big Horn Range, Wyoming Craton crystalinks.com/bighorn.html
Yellowknife Nuclei, Northwest Territories, South shore of Lake Yamba Deposits of gneiss derived monazite, Believed to be 2,200-2,340 million years old. link
Superior or Keewatin Nuclei, north of Lake Superior
Guyana Highland Nucleus, in South America, in the Guiana Shield Craton
Dnieper Plateau Nucleus in Ukraine,
Dharwar province in southern India (Dharwar Craton)
Guinea, probably part of the Man Shield on the southwest corner of the West African Craton. This is part of the Guinea Highlands, which is the source of the Niger.
Tanganyika
Rhodesian highlands in Africa
Southwestern Australia (Yilgarn Craton), 4,270 million years old
Any additional information greatly appreciated.
