| Abstract: | REE, Th, U, Pb and Hf have been determined in nine selected samples from the Marda Archaean calc-alkaline suite. Data are consistent with field relationships and major and other trace element abundances, which suggest a crustal origin for the Marda magmas. REE patterns are analogous to continental margin (Andean) calc-alkaline volcanic suites and are not similar to those from other Archaean areas. |
