Etude du cadre stratigraphique régional de la roche en place et des sédiments de surface sous le lac Ontario par l' interprétation de 2550 km de profils de sismique réflexion. Mise en évidence et cartographie de 5 unités recouvrant le substratum
paléozoïque. La sismique réflexion a aussi permis de délimiter la configuration de la surface du socle et des vallées pré-glaciaires qui y sont entaillées.

Here two commercially-acquired seismic reflection profiles are used to establish the structure and stratigraphic relationships between the frontal part of the orogenic belt, the foredeep and foreland regions in the offshore continuation
of the Apennine system in the northern Ionian sea. Given the proximity of this study area, the tectono-stratigraphic relationships imaged on these seismic lines are likely to provide good analogues for Neogene basins and depositional systems for much
of the Apennines onshore. Syntectonic basins are narrow, long-range stratigraphic continuity is likely to be the exception rather than the rule. This challenges some of the assumptions behind existing tectonic models for the Apennines and similar orogens. - (NF)
are to interpret the stratigraphic sequence offshore in terms of the processes of ice retreat and of postglacial sedimentation, to compare the offshore to the onshore stratigraphy and interpret that in terms of processes, and to relate the results to the known
The purpose of this work is the reconstruction of the crustal tectono-stratigraphic setting of the area extending from the Tyrrhenian coast to the M. Cetona thrust. The results obtained are very important and decisely innovative as regard
High-resolution seismic stratigraphy has been applied to the interpretation of the stratigraphic architecture of the Late Pleistocene and Holocene successions on the continental shelf and upper slope of the Gulf of Castellammare, North-Western

The glacier stages in the region were mapped extensively and in detail. These field-works were complemented by drillings, diggings as well as seismic and stratigraphic research, thus resulting in a glacier history of the region. In supra-regional

This paper discusses the correlation between the seismic records and sediment samples, and provides age estimates for the buried sediment packets recorded by seismic reflectors. The AA. used sequence stratigraphic analysis of the seismic record

A high-quality, large 3D seismic data volume collected in a highly channelized stratigraphic series found in the upper 500 ms of the Sunda Shelf in offshore Indonesia was used to map incised valley development on this shelf. Defined on a seismic
