1
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm Randell Stephenson (University of Aberdeen), Scott Jess (University of Aberdeen), Søren Nielsen (Aarhus University), Martyn Stoker (Arbitrary Oval, Adelaide) and others? Premise: Intraplate basin/structural inversion is a good marker of (“far-field”) tectonic stress regime changes that are linked to plate boundary reorganisations.
2
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm The premise is well-established in the literature. How Late Cretaceous- Palaeocene basin inversion has occurred in north-central Europe can be linked explicitly with the timing and style of plate break-up in the North Atlantic.

4
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm Two papers published on line this week (this being one of them) have documented intraplate structural inversions and interpreted them thus. Tadayon et al., in press. The post-Eocene evolution of the Doruneh Fault region (Central Iran): the intraplate response to the re-organization of the Arabia-Eurasia collision zone. Tectonics.
5
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm Approach: The “ubiquitous” existence of Late Cretaceous-Palaeocene basin inversion is well-documented in continental Europe (e.g., Peter Ziegler). from Peter Ziegler’s atlas (1990) Late Cretaceous-Palaeocene: intraplate inversion structures
6
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm This map will be extended to include the offshore parts of the North Atlantic regime, including the Labrador-Baffin domain (and be modified/updated onshore). from Peter Ziegler’s atlas (1990) Late Cretaceous-Palaeocene: intraplate inversion structures
7
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm New maps will be compiled for (postulated) Eocene-Oligocene and younger (Miocene?) events if sufficient documentation is uncovered. Includes an expected dash of serendipity. from Peter Ziegler’s atlas (1990)
8
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm The key tectonic expression of the Eocene-Oligocene plate reorganisation event is the intraplate Eurekan Orogen (“basin inversion”) but its effects are widespread throughout the North Atlantic regime and is contemporaneous with other major intraplate shortening structures like the Crimea-Greater Caucasus orogeny and other Tethyan belt inversion structures.

A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm Sources: Published materials including NAG-TEC Atlas, GSL Special Publication, Baffin papers (including unpublished GSC seismic interpretations)
10
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm Discussion and conclusions: (i) correlations in the North Atlantic regime and inferences for basin cyclicity and so on….
11
A review of Late Cretaceous-Cenozoic intraplate basin inversion in the North Atlantic-western Tethys realm Discussion and conclusions: (ii) correlations world-wide and implications for “global tectonics”: cause and effect for plate tectonics
