Subduction Impacts on Extension in Western Turkey

I am interested in the processes of post-collisional extension that led to the formation of the Menderes Massif, the largest metamorphic core complex on Earth. By studying the igneous and metamorphic rocks in this region using geochronology and thermobarometry, I aim to understand the geological processes driving extension in the continental lithosphere. This research inherently involves investigating the dynamics of subduction zones, particularly focusing on the Hellenic arc in the Aegean region. This area serves as a type-locality for understanding various aspects of subduction dynamics such as slab tear, slab fragments, drips, and transfer zones. The study of these processes are linked to significant geohazards, including large-magnitude earthquakes, tsunamis, volcanic eruptions, and landslides, which are critical for assessing seismic and volcanic risks in the region.

By determining the timing and nature of subduction initiation along the Hellenic arc, I aim to shed light on broader questions related to plate tectonics and Earth’s geological history. This includes understanding the impacts of subduction on mantle convection, surface conditions, climate, seismicity, magmatism, and ore deposits over geological time scales. Additionally, I investigate the implications of younger estimates for subduction initiation on existing tectonic models and reconstructions of the Aegean-Anatolian region’s tectonic history.

Overall, this research contributes to advancing our understanding of fundamental geological processes such as extensional tectonics and subduction dynamics, with implications for hazard assessment, plate tectonics, and Earth’s geological evolution.
