The dimension stone production ratio is about 15 % in the Karaburun limestone quarries. Thus, opening of a quarry in limestone for only dimension stone production is not very profitable economically at present. For example, in the Quarry 5 (Q5) where approximately 8000 m 3 /year limestone blocks are produced (Fig. 1).
