Deciphering rock surface origins in a karst cave: insights from the Rača Cave, Lastovo, Croatia

This paper outlines a comprehensive fieldwork methodology for discerning the origin of rock surfaces within a karst cave environment. This methodology is particularly utilized in a cave with breakdown morphology. Using Rača Cave in Lastovo, Croatia as a case study, we explore geological and morphological features through advanced surface analysis. The approach involves meticulous measurement of rock discontinuities, joint patterns, and surface formations. Cost-efficient and time-efficient data collection and processing during field-work were undertaken with FieldClino Move and Polycam applications on smartphones. Visualization techniques were employed to elucidate the interplay between erosion, deposition, and speleogenetic processes.
