A precise Sm–Nd age of 2,790±30 Myr and an initial ratio corresponding to ɛNd = +3.4±0.6 has been determined for the Kambalda sequence from the eastern Yilgarn Block of Western Australia. The high initial 143Nd/144Nd implies a long-lived light rare-earth element-depleted (high Sm/Nd) source for the Kambalda volcanics and therefore provides definitive… CONTINUE READING
