Abstract:

Here, we synthesize sedimentological, geochemical and paleontological data from the Permian–Triassic succession of southwestern Türkiye, putting it into a consistent stratigraphic framework and incorporating 3D open-access virtual outcrop models with a virtual field guide to improve the accessibility, reproducibility and sustainability of fieldwork findings. This approach was necessary, because the accessibility and findability of the Permian–Triassic successions in Türkiye is difficult due to the lack of information or inconsistencies in publications. The new virtual models allow scientists and the public to access the virtual models online, visit the sections, investigate reported sedimentary structures and fossils, and even prepare for their own fieldwork in the future. Furthermore, these sections are changing in an evolving landscape, due to road development altering the outcrops and natural weathering processes. Some of the sections are also extremely hazardous and using drones to create virtual models, reduces the risks whilst undertaking fieldwork. In addition to digitizing the sections, we put all existing paleontological and geochemical data into a consistent framework to allow for integrating new data into previous datasets and paving the way for quantitative analyses. An extinction pulse algorithm was then utilized to determine the nature of the mass extinction event, where a single pulse of extinction was recognized during a “transitional oolite” in the latest Permian. The limited availability of geochemical proxies, however, hinders our understanding of the environmental drivers of the extinctions.
