U-Pb age of Kaapvaal craton titanite: geotectonic interpretation and correlation with the Karelian craton
The results of dating of Kaapvaal Craton titanite are reported. It is shown that metamorphiczircon, apatite, amphibole and garnet in the Neoarchaean tectono-thermal activation belt in the eastern Swaziland terrane have an age of ca. 2.74 Ga, while the age of titanite outside the belt is Palaeo-Mesoa...
