Abstract: This study aims to examine the formation mechanisms of fairy chimneys located within the boundaries ofEşme district (Uşak province) through a multilayered geological and geomorphological approach. Unlike classicalexamples that typically develop in volcanic tuffs, the fairy chimneys in the study area formed through the interactionof lithological heterogeneity, differential weathering, and surface runoff erosion processes acting on weaklyconsolidated alluvial and colluvial deposits derived from fluvial sedimentation.The local deposits are characterised by alternating layers of conglomerate, sandstone, siltstone, and partiallyclaystone. The presence of relatively resistant zones within these sedimentary rocks constitutes one of the primarylithological controls on fairy-chimney development. Linear erosion along steep slopes, generated by the drainage network, accelerates selective erosion of the less resistant rocks; consequently, columnar structures develop beneatha protective cap layer due to contrasting erosion rates.In this study, field-based morphological observations, sedimentological features, slope and profilemeasurements, and DEM-supported morphometric analyses were integrated to reveal the formation processesfrom multiple perspectives. The findings indicate that these fairy chimneys represent geodiversity elements that aremorphogenetically unique and directly governed by local lithology.The scientific interpretability, educational potential, aesthetic quality, and landscape integrity of these landformsrender them not only geomorphological features but also geological heritage elements that merit protection andpromotion within the framework of geotourism. The fairy-chimney formations identified in the Uşak–Eşme regionare a valuable contribution to the inventory of such landforms in Türkiye. The study also recommends the evaluationof these features within sustainable geotourism policies.
