ICE FT 05 | Tectonic and Sedimentary History of a Basin Margin, Isle of Wight
Geological Society of London (GSL)
Thursday, 12 October – Saturday, 14 October 2017, 6:00 p.m.–10:00 a.m. | Sandown, England
Who Should Attend
Geologists with an interest in the relationship between sedimentation and tectonics.
Objectives
To trace the extensional (Cretaceous) and inversion (Paleogene) history of a major basin-bounding fault using reworked clasts and fossils.
Course Content
The coastline to the east of Sandown, Isle of Wight, exposes a continuous section from the Lower Cretaceous (Barremian) to the Oligocene (Rupelian), and traverses a major E-W deep basement fault (Hercynian). This fault moved normally during Lower Cretaceous times, defining the northern margin of the Channel Basin, and floods of Jurassic clasts and fossils were reworked into the Barremian and Aptian. Jurassic ammonite zonal species are found in inverted order, and permit an estimate of rate of fault movement. The structure was quiescent during the Late Cretaceous (Chalk deposition), but inverted in the Eocene, defining the southern boundary of the Hampshire Basin. The detailed history of this uplift can be traced from the distribution of reworked earlier Paleogene clasts into younger Eocene sediments.
The outcrops of Cretaceous and Paleogene sediments are amongst the most spectacular in Europe, and a detailed stratigraphic, sea-level and paleoclimatic story will be provided.
