“…Moreover, NT has proved especially successful in providing high-resolution images, in the order of magnitude of tenths of a millimetre, for features within a rock sample that is several centimetres in size, and also of imaging hidden interior features that X-ray and gamma-ray imaging have failed to reveal (Schillinger et al 1996). Although most applications of NT have focused on metals, several studies have centred on imaging the internal composition of geological samples (e.g., Winkler et al 2002;Vontobel et al 2005;de Beer et al 2007;Longridge et al 2009). Indeed, NT has proved to be an important complement to X-ray tomography in determining or validating existing data concerning some of the important physical properties of rock.…”

Neutron Tomographic Assessment of Incisions on Prehistoric Stone Slabs: A Case Study From Wonderwerk Cave, South Africa*

et al. 2012

This study presents the application of neutron tomography to the analysis of ironstone slabs found in a late Earlier Stone Age context (Fauresmith industry) at the back of Wonderwerk Cave, Northern Cape Province, South Africa. These slabs have markings on the surface that might be anthropogenic, and thus significant to understanding the emergence of human symbolic behaviour. Neutron tomography proved to be an effective tool for distinguishing surface incisions from lines that are the expression of internal fissures in the rock.
