Abstract

The Bushveld Complex is a 2.06 Ga layered suite of mafic and ultramafic rocks. These rocks are believed to have formed from several magma pulses covering an estimated 65 000 km2. Wireline geophysical logs of density and magnetic susceptibility data have previously been studied using wavelet analysis. This analysis has revealed cyclicity in the physical property data, which has been attributed to magmatic pulses which resulted in layer growth, analogous to sedimentation in a sedimentary basin environment. These studies were carried out in the Northern Limb of the Bushveld Complex. This study expands on previous work, making use of three boreholes from the Western Limb. Results once again show cyclicity in density data, with strong correlations at a wavelength of 150 m, which is similar to the wavelength of the cyclicity discovered previously in the Northern Limb. Analysis is currently being done on data from the Eastern Limb of the Bushveld Complex.
