Transient landscape and stratigraphic responses to drainage integration in the actively extending central Italian Apennines

摘要: Abstract Drainage networks in continental rifts are generally reported as dynamic features that produce transitions between endorheic and exorheic conditions. While this is of major importance for landscape development, sediment dispersal, basin stratigraphy, the controls drainage network evolution across an array normal fault bounded basins still not well understood. In study we use central Italian Apennines – area has been affected by active faulting regional uplift over last ~3 Myrs to determine on its impact transient stratigraphy. We compile previously published stratigraphic fault-related data with new geomorphological constraints Aterno River system (~1300 km2), which a wealth collected following destructive L'Aquila earthquake 2009. compilation demonstrate how different along river were initially isolated during Early Pleistocene but became fluvially integrated one another Adriatic coast ca. 1.2 0.65 Ma. conclude spatial temporal pattern integration mostly explained long-term increase water supply relative subsidence due Middle climatic transition, progressive topography, transport down-system occurred.
