| Citation | Moorbath is the leading British geochronologist; he set up (1956-58) and has since directed the Age & Isotope laboratory in Oxford. He and his collaborators demonstrated the great gap between Scourian (2600 m.y.) and Laxfordian (1600 m.y.) gnesisses in N.W. Scotland; established the basic mineral age pattern of the Scottish and Irish Caledonides (420-450 m.y.) and interpreted it as a cooling-uplift interval; by pioneer Pb isotope studies of ancient gneisses, showed that much of the Lewisian existed over 2900 m.y. ago; dated the oldest rocks yet known on the earth (more than 3800 m.y.) from W. Greenland; applied the Rb Sr method to date Torridonian sediments; elucidated the complex history of British & Scandinavian lead ores; showed that the Tertiary acid magmas of Skye are remelted Lewisian gneisses (more than 3000 m.y.) whereas those of Iceland are of mantle origin; showed that Rochall is underlain by continental crust as implied by Bullard's Atlantic fit. |
