The role of rock surface hardness and internal moisture in tafoni development in sandstone (2011)
Journal Article

The development of cavernous weathering features such as tafoni remains poorly understood. In particular, the roles played by internal moisture and case hardening remain unclear. In this study, Electric Resistivity Tomography (ERT) has been used to m... Read More about The role of rock surface hardness and internal moisture in tafoni development in sandstone.

Sandstone weathering, electrical resistivity tomography, and the deterioration of San rock art in the Golden Gate Highlands National Park, South Africa (2011)
Thesis

Electrical Resistivity Tomography (ERT) is a novel technique which can be used to build up a 2D pseudo-section of resistivity distribution of a porous material. Here, it is used to visualise internal moisture regimes by measuring the resistivity dist...
