All these parameters are very important for decision‐ making in the initial phase of quarry investment since these factors control the potential of the location for dimension stone deposit and type of excavation. The methodology is also applicable to hydrogeological (fractured aquifers), geotechnical, civil engineering, and engineering geology research (rockfalls, construction of roads, viaducts, railways, bridges, tunnels, etc.) where knowledge about fracture systems in the rock mass is crucial for further works. Citation: Pavičić, I.; Galić, I.; Kucelj, M.; Abstract: The successful exploration of dimension stone mainly depends on the quality, size, and Dragičević, I. Fracture System and shape of extractable blocks of dimension stone. The investigated area is in the Pelješac Peninsula Rock‐Mass Characterization by (Croatia), in the External Dinarides orogeny, built from thick carbonate succession, characterized Borehole Camera Surveying: by relatively small deposits of high‐quality dimension stone.
