Abstract This study reports three K/Ar ages on celadonite, a dioctahedral K-Fe mica, in the Proterozoic North Shore Volcanic Group (NSVG) of Midcontinent Rift northeastern Minnesota. Celadonite formed during beginning posteruptive, low-temperature conditions at temperatures<100°C and with input meteoric water. between 1062±16 Ma 955.0±12 document remarkably long posteruptive thermal hist...
