Nuvvuagittuq greenstone beltzxc.wiki
The Nuvvuagittuq Greenstone Belt is a rock unit on Hudson Bay in northern Canada in the province of Québec which is one of the oldest rocks on earth possibly up to 4.4 billion years old.It contains microscopic structures that could be the oldest fossils on earth.
Neodymium-142 Evidence for Hadean Mafic Crust Science
· Neodymium-142 data for rocks from the Nuvvuagittuq greenstone belt in northern Quebec Canada show that some rock types have lower 142Nd/144Nd ratios than the terrestrial standard (ϵ142Nd = –0.07 to –0.15). Within a mafic amphibolite unit 142Nd/144Nd ratios correlate positively with Sm/Nd ratios and produce a 146Sm-142Nd isochron with an age of batchmode documentclass fleqn 10pt

Response to Comment on "Neodymium-142 Evidence for Hadean
· Andreasen and Sharma raise concerns about the neodymium-142 data and age that we reported for rocks from the Nuvvuagittuq greenstone belt in Quebec Canada. We agree that the issue of accurate mass fractionation correction is important but stand by our discussion of this issue in our original report and our conclusion that the variation in 142Nd/144Nd ratios reflects the decay of
