Combining all available data for the Magondi Basin, the Limpopo Belt between the Zimbabwe and Kaapvaal cratons, and the Kheis Belt on the southwestern margin of the Kaapvaal craton, a new tectonic model is presented for the assembly of the Kaapvaal and Zimbabwe cratons at ca. 2.1–2.0 Ga.These cratons along with the Archaean cratons in West Africa and …

The Fractal Distribution of Gold Deposits: Two Examples …

Gold deposits in two study areas in the Zimbabwe Archaean craton have fractal spatial distributions over a length scale from 2.5 to 25 km. The number of squares of side d necessary to cover every deposit is proportional to a power of the length of the square, and the number of deposits within a circle of radius r is proportional to a power of the radius.
