Abstract
Salt weathering represents a major cause of damage on stone monuments worldwide. However, processes of salt weathering still cannot be explained satisfactorily. Further systematic investigation of stone monuments is required for the improvement of knowledge on active salt weathering processes and controlling factors. Assessment of the dynamics of salt crystallization–dissolution processes is a focus of modern salt weathering research. The overall aim of the ‘petraSalt’ research project are real-time/real-scale weathering models that depict characteristic interdependencies between stone properties, monument exposure regimes, environmental influences, salt loading, salt crystallization–dissolution behaviour and salt weathering damage. The rock-cut monuments of ancient Petra in Jordan were selected for studies. A main part of the project is the joint evaluation of salt load and environmental conditions acting on it, allowing a differentiated, depth-dependent quantification of the complex salt crystallization–dissolution processes, considering diurnal and seasonal variation. The approach is exemplified.
