Conservation of Rock Art. Proceedings of the International Workshop on the Conservation of Rock Art, Perth, September 1977 (1978), pp. 54-63
Discusses the various techniques used to establish the causes of rock art deterioration. The first group of techniques is used to establish site parameters and includes photographic recording, petrographic analysis of the rock type, analysis of pigments, microclimate data, ground water composition and ultra violet radiation levels. The second group includes the more sophisticated techniques which can be used to give additional information on particular aspects of site deterioration and includes electron probe micro analysis, micro XRD analysis, scanning electron microscope analysis of surfaces, transmission electron microscope analysis of pigments, permeability of rocks and surface coatings, and physical testing of rock strength.
