New U-Pb data on zircons from the Amalia greenstone belt Southern Africa: insights into the Neoarchaean evolution of the Kaapvaal Craton
Evidence for the existence of Neoarchaean greenstone rocks in the western part of the Kaapvaal Craton is provided by ID-TIMS and SHRIMP U-Pb age data on zircons from supracrustal rocks of the Amalia greenstone belt. Although all the units described from the Amalia greenstone belt might not be coeval, an age of 2750.1 ± 4.6 Ma found for two samples appears to be the best estimate for the deposition of this part of the Amalia greenstone belt sequence. These samples also contain younger zircons,...[Show more]
