The Bozdag High is a metamorphic core complex located between the Gediz (Alasehir) and Kucuk Menderes grabens in the Western Anatolia Extensional Provine. The region is struturally ontrolled by low-angle Gediz Detahment Faults (GDF) and high-angle normal faults, whih play a fundamental role in its geomorphologial evolution. Understanding how these fault systems interat to shape uplift, drainage reorganization, and landsape dynamis remains an open sientifi question. This study utilizes GIS-based morphometri analyses of 53 drainage basins and mountain fronts to quantify the spatial variations in uplift and fault ativity. By integrating geomorphi indies (e.g., -index, ksn, Smf, Vf) with analytial hierarhy proess (AHP) models, we assess relative tetoni ativity and investigate the kinemati evolution of fault-bounded bloks. Our findings reveal that the Bozdag High experiened distint rotational phases before and after the ativation of high-angle faults, transitioning from an initial detahment-dominated extensional system to a segmented fault network. Additionally, Bozdag High exhibits ontrasting tetoni ativity between its northern and southern flanks. While the northern flank, faing the Gediz Graben, experienes higher uplift rates and stronger tetoni foring, the southern flank, adjaent to the Kucuk Menderes Graben, exhibits relatively subdued tetoni ativity and inreased erosional modifiation. The western setion of the eastern flank shows a more rapid uplift trend toward the east, whereas the southern flank displays signifiant surfae tilting. Geomorphi evidene suggests that sequential fault ativity and strain partitioning ontrol differential uplift, drainage divide migrations, and basin asymmetry. Asymmetri basins in the southern setor, haraterized by high hypsometri integral (HI) and low normalized steepness index (ksn) values, suggest a balane between erosional proesses and tetoni uplift. In ontrast, regions with ongoing rapid uplift exhibit higher ksn values and ative knikpoint formation. These results provide new insights into the interation between low-and high-angle fault systems and ontribute to the broader understanding of tetoni evolution in extensional provines. These new insights inlude the identifiation of spatially variable uplift and rotation patterns aused by sequential ativation of low- and high-angle faults, revealing how blok tilting and strain partitioning have shaped drainage reorganization and landscape evolution in the Bozdag High.
