This study investigates the Khur Basin in central Iran, a crucial area for understanding landscape history, past environmental changes, and potential human migration. By analysing the sedimentary archives and mapping landforms, six stages of landscape development were identified, linked to the climate shifts over the late Quaternary period. The findings provide a detailed understanding of how a desert environment, including alluvial fans, dunes, and playas, developed in response to changing climates.

We studied snails from Holocene river sediments of the upper Alazani River in the southeastern Caucasus. Since no natural floodplain forests existed in the river valley until ca. 4500 years ago, our snail data confirm a formerly suggested regional settlement center from the ca. 8000 years unknown thus far. Furthermore, increasing proportions of water-related snails for ca. 4000 years indicate a shift of the river course possibly linked with the formation of the Greater Caucasus.
