The aim of this study was the examination of control factors for weathering processes in two different study sites in Tafraoute and on the Dachsteinmassif. We investigated tafoni developed in in the Tafraoute region through an exploratory, two-week multi-method field campaign. The results derived from very different techniques mutually support one another. Salts and moisture are concentrated near the base of the investigated tafoni, probably due to a saturated pore water body around the base of rock tors. Salts are accumulated close to the rock surface in tafoni, but not on the surrounding rock surfaces. Within a tafone, areas of higher humidity also display increased salt concentration near the surface. Two pathways of salt transport in and around tafoni are assumed based on the data: infiltration with rainfall on the top and around tors and boulders, and capillary rise from saturated pore water bodies to the surface. Rock temperatures are one of the key factors for frost weathering but the question of their spatial distribution on a regional scale remains open. We adapted the program package WUFI®, designed to calculate energy fluxes in building walls, for application at natural rock faces. We determined physical rock properties and local meteorological parameters as input data for the simulations at our study area (Dachstein Mountains, Austria; highest peak at 2998 m). From the input data we calculated annual temperature progressions in different elevations, orientations and slopes. For verification, temperatures at different depths were measured with iButtons and surface temperatures were determined from infrared images. The model runs were used to calculate frost parameters and to define the (thermal) frost weathering potential. Frost weathering potential increases with elevation and correlates with orientation, with north faces being more affected than south faces. The effects of snow cover and of different hypothetical frost cracking windows are discussed.
