U-Pb baddeleyite dating of intrusions in the south-easternmost Kaapvaal Craton (South Africa) : revealing multiple events of dyke emplacement
This study presents U-Pb baddeleyite ages for five dolerite dykes and one sill in the Mesoarchean granitic basement of south-easternmost Kaapvaal Craton in northern KwaZulu-Natal, South Africa. The oldest dyke is ENE-trending, and is dated to 2729 ± 5 Ma. One ENE- and two SE-trending dyke are dated to 2580 ± 3 Ma, 2574 ± 5 Ma and ˃2517 ± 5 Ma (minimum age for the latter given by the 207Pb/206Pb da
