### Suitability of the Investigated Rocks for Use as Dimension Stones  
Dimension stones are highly demanded for their durability, appearance, and ability to be polished, making them ideal for various architectural and decorative applications. In this regard, the investigated rock types were systematically evaluated to determine their suitability for use in the dimension stone industry. To assess the quality of these rock types, the quantitative classification system developed by [PERSON] et al. [4] was adopted, providing a structured framework for categorizing the materials based on selected rock properties. The analysis results, presented in pie charts (Figure 4), reveal that the majority of the rock materials were classified as high or very high quality, suggesting that most of the investigated rock types have desirable characteristics for commercial use as dimension stones in Turkey. Figure 4 also highlights the potential uses of these rock types, revealing their suitability as valuable resources for construction and decorative stone applications.  
A closer examination of specific rock types reveals notable differences in rock quality. For example, gabbro-type rock materials (L7) demonstrated the highest quality across the evaluated rock properties, making them one of the best choices for dimension stone applications.  
Similarly, rocks from the L10 location were found to be of high quality for dimension stone applications. In contrast, the quality of tuffs and ignibrites (L2) showed greater

variability, depending on the rock properties assessed. When evaluated by \(\rho_{d}\), these rocks generally exhibited moderate quality. However, based on their BAV values, they received higher quality ratings, making them suitable for applications that required strong abrasion resistance (Figure 5). Based on the provided information, it is concluded that most of the rock types seem appropriate for dimension stone applications. Therefore, the investigated rock types should be further investigated in more detail from the viewpoint of engineering economics.  
These findings highlight the importance of evaluating rock materials through critical rock properties to forecast their performance and comprehend suitability for use as dimension stones. By using both \(\rho_{d}\) and BAV values, the suitability analyses provide a more comprehensive view of the characteristics of each rock type, ensuring that the selected dimension stones can meet the needs of the dimension stone industry in Turkey.
