The Coevolution of Tectonics, Climate and Biodiversity in Central Asia
Session ID#: 74413
Session Description:
Crustal deformation and mantle dynamics have an extraordinary impact on climate through surface uplift and erosion. Conversely, climate can influence deposition, denudation, topography and biodiversity. Central Asia holds some of the world's largest and most extensive mountains, deserts and biodiversity hotspots. Throughout the Phanerozoic, the region witnessed the construction and reactivation of the Central Asian orogenic belt, the formation of the Tibetan-Pamir-Iranian-Anatolian plateaus, the Cenozoic retreat of the Para-Tethys Sea and progressive Central Asian desertification, the development of monsoons, Westerly jet and Siberian high, which all impact biotic turnovers with steppe and mammal extension across Eurasia. This session aims to explore the coevolution of tectonics, climate and biodiversity in Central Asia through time, emphasizing the processes, consequences and interactions. A wide range of data and model approaches that address the central theme are encouraged as this session aims to foster a cross-disciplinary discussion.
