Geophysical Investigation Into The Entabeni And Palmietfontein Granites, And The Schiel Alkaline Complex In The Northern Transvaal And Venda

The late Precambrian and early Protozoic was an important period in the history of the Kaapvaal Craton since it not only represents the final episode of the Limpopo metamorphic event at 2670 Ma (Van Reenen et al., 1988) but also the intrusion of large volumes of alkaline granite magmas, the so called “young granites” took place between 2650-2400 Ma, represented by the Turfloop, Da Maranda (± 2650 Ma); Moletsi, Lunsklip, Uitloop Shamiriri (± 2600 Ma); Smitskraal, Matlala (2500 Ma) and the youngest ones Palmietfontein (± 2456 Ma) and Entabeni (±2000 Barton pers. comm.) (Barton et al., 1983; Van Reenen et al., 1988).
