... disturbed beds, with convoluted bedding and fluid escape structures, are interpreted as seismites. Immediately above, three lenticular, fining-upward, bioclastic grainstone beds, interbedded with argillites, are interpreted as tsunamites. In these beds, hummocky cross-stratification and grading indicate...

...G. Shanmugam Abstract The genetic term tsunamite is used for a potpourri of deposits formed from a wide range of processes (overwash surges, backwash flows, oscillatory flows, combined flows, soft-sediment deformation, slides, slumps, debris flows, and turbidity currents) related to tsunamis...

... Abstract Shallow drilling in the lagoon of the Cabo de Gata area proved sedimentary evidence for a palaeo-tsunami along that part of the Spanish Mediterranean coast. Several coarse-grained intervals form fining-up and thinning-up sequences that are interpreted as tsunamites. Inland-extending...

... ABSTRACT An unusual deposit at the Cretaceous-Paleogene (K-Pg) boundary within the Adriatic carbonate platform shallow-water succession is interpreted as a major tsunamite, and a possible mechanism that links it to the Chicxulub asteroid impact on Yucatan (Mexico) is speculated. Although the K...

These findings demonstrate that a catastrophic event around the Permian-Triassic boundary in Brazil created one of the world’s most extensive seismite-tsunamite couplets...

Taphonomic traits (e.g., articulation, rounding, fragment angularity) of all bivalve material >5.6 mm were quantified for eight sample horizons, and compared with a tsunamite from Caesarea, Israel. Some of the taphonomic characteristics between the shell beds from these two different depositional settings...
