There are two phenomena that would have had a detrimental effect on natural gas contained in strata of the Ecca Group, in that at least some of the contained gas would have escaped, or at least been redistributed. These phenomena are (i) deformation features associated with the Cape Fold Belt (CFB) and, (ii) large scale intrusion of dolerites during the Mesozoic.
Deformation features of...

The expected decant rates at rehabilitated opencast pits are usually estimated by simply assuming a high recharge value (15% - 20% of the mean annual precipitation) through the spoils. This approach is based on the assumption that the inflow volumes of groundwater are balanced by the outflow volumes. However, using this standard approach for decant estimation at the mine under investigation...

According to Einstein's General Theory of Relativity (GRT), spacetime curvature in the vicinity of a large mass such as the Sun will cause light to bend. The measurement of light from stars close to the Sun during a total solar eclipse provides an opportunity to test this light bending, thus evaluating GRT. During 1919, Eddington performed such an experiment, obtaining results which supported...

The Coaltech Research Association funded an airborne magnetic and radiometric survey over the Karoo-age Ellisras Basin in the Northern Province of South Africa in 2008. The Waterberg Coalfield, which is destined to become the major source of energy in South Africa in the future, is situated in this sedimentary basin. Interpretation of the processed geophysical datasets has added significantly...
