Benchmarks and sediment source(s) of the 1755 Lisbon tsunami deposit at Boca do...

Standardizing the signature of tsunami deposits has been identified as a major limitation for the identification of paleo-tsunami deposits. This limitation mostly arises from the strongly source-dependent nature of these deposits, which in turn determines their composition and depositional architecture, and from the effect of the local morphology of the corresponding depositional environment. Here, we provide...

Testing rock magnetic and AMS method in tsunami and storm-induced deposits

Identification of tsunami deposits and their impact on coastal zones : a study ...

Morpho-sedimentary evidence of Holocene tsunamis in Southwestern Spain estuarie...

Los estuarios constituyen sistemas costeros excelentes para registrar tsunamis a través de un amplio tipo de evidencias geológicas. Este trabajo revisa y resume las evidencias de tsunamis prehistóricos e históricos en los quatro principales estuarios del suroeste de España. Las más frecuentes son erosión de playas y retroceso del litoral, ruptura y desbordamiento de flechas arenosas y depósito de capas bioclást...

Benchmarks, sediment source and hydrodynamics of the 1755 Lisbon tsunami deposi...

Standardizing the signature of tsunami deposits has been pointed as a major limitation on the identification of paleo-tsunami deposits. This limitation majorly arises from the strongly source-dependent nature of these deposits, which in turn determines their composition and structure, and from the effect of the local morphology of the corresponding depositional environment. Here, we provide new high-resolut...

Magnetic fingerprints of stalagmites

Dating stalagmite usi ng paleomagnetic methods is still in its early stage of development. Questions still remain regarding the nature and origin of the magnetic carriers and the reliability of the natural remanent magnetization preserved within the thin carbonat ed laminations of stalagmites. Here we apply high - resolution rock - and paleo - magnetic methods on two (altered and preserved) stalagmites in order...

Identification of Tsunami deposits and their impact on coastal zones : a study ...

Tsunamis are unforeseeable phenomena and therefore one of the most devastating natural disasters in terms of human and economic losses. Their impact on coastal and nearshore zones is substantial and need to be accurately evaluated to improve their prevention and management. In the last decades, numerous investigations focused on the identification of paleotsunamis in order to evaluate their frequency in the geo...

Standardizing tite signature of tsunami deposits has been pointed as a major limitation on the identification paleo-tsunaml deposits. This limitation majorly arises from the strongly source-dependent nature of these deposits, which in turn determines their composition and Structure, and from the effect of the local morphology of the corresponding depositional environmemt. Here, we provide new high-resolution mi...

The pre-KPB interval: sedimentary record of a major Deccan Traps pulse ?

The KPB crisis is one of the major biological crises that affected the Earth at Phanerozoic times. There is still an acrimonious debate on the nature and origin of this mass extinction: proponents of the idea that large bolide impacts caused most of the Phanerozoic mass extinctions are opposed to those who favoured a terrestrial origin linked to continental flood basalt eruptions of the Deccan Traps. The major ...
