Influence of joint spacing on weathering and soil formation on a morphologically diverse sandstone cliff (Stołowe Mountains tableland, SW Poland)
Abstract
The research presented in this paper was conducted in the Stołowe Mts. and addressed litho-structural controls on sandstone decay at Białe Skały. We tested the working hypothesis that densely jointed, disintegrated zones exhibit increased moisture that fosters arenization, resulting in reduced surface strength. Geomorphological mapping, structural measurements, Schmidt-hammer rebound testing, and rock-moisture surveys with three handheld metering devices of differing penetration depths were undertaken. Rebound values confirmed significantly lower surface strength in disintegrated zones. Moisture measurements yielded equivocal results at different depths; only near-surface readings indicated higher values after antecedent rainfall. Together with deeper, organic-rich soils in disintegrated sectors, the evidence supports joint-guided weakening and recessed cliff development. Further depth-resolved moisture monitoring is recommended.
