There are very rich natural stone resources in Turkey, and high quality products have been produced for the world market with modern production methods from these resources in recent years. Turkey's natural stone export revenue in 2022 has exceeded 2 billion dollars. This study was carried out to emphasize the effects of tectonic-controlled structures (faults, cracks, cracks, folds…) and sedimentological features on the quarry productivity in the marble quarries in Bilecik, and to determine the geological factors that affect the development of the patterns observed in the marble quarries, and to explain the effects of these patterns on the marble quarrying. Within this scope, stratigraphic, sedimentological, structural and engineering geology studies were conducted at different stratigraphic levels in the quarries producing marble in the region. The marble patterns observed in the quarries in this region were determined as Bilecik Beige (Bilecik Beige-oolithic, Bilecik Beige-reefal, Bilecik Beige-fossiliferous, Bilecik Beige-nonfossiliferous) and Rosalia (Rosalia breccia, Rosalian stylolitic). The geological parameters controlling the formation of these patterns and the quarry productivity are (1) the stratigraphic level at which the marble quarry is excavated, (2) the lithological and sedimentological characteristics of the rocks, (3) the characteristics of the faults (types, dip directions, dips) passing through or near the quarry, (4) fracture-crack density in the region, (5) secondary mineral developments and the abundance of these mineral veins.
