Uniclinal Structural Control
August 29, 2004
I came across this example while on holiday in South Africa during which time I collected numerous images for teaching purposes. The photograph illustrates the influence of uniclinal structural control. The hill in the middle ground consists of harder layers of quatzite tilting to the left (west in this instance). The geology is that of the Waterberg Formation and it lies on the eastern side of the Waterberg mountain chain. Subsequent denudation has created this assymetrical hill, a cuesta or homoclinal ridge. Note the steep side (or scarpslope) where the strata has been breached and the gentler slope (dipslope)where the landsurface coincides with the upper bedding plain.
