British Geology Assessed Practical by Alexander Hazel
The Isle of Wight is an area of
geological interest due to its
position relative to Europe for the
Alpine Orogenic event, as part of
Section 2
the UK geological history, and
due to its relation to the Atlantic
Ocean nearby. The cross sections Figure 1
show a distinctive folding pattern
of anticlines and synclines on
both sections. They are not Section 1
symmetrical and are most likely
associated with the rifting that
occurred at the formation of the
Atlantic in the early Cretaceous.
The rifting caused extensional
faults to form creating localized
basins in southern Britain as well
as the Isle of Wight. The basin
was inundated by the chalk seas
of the late Cretaceous and
Feedback
extensional faulting halted.
Adequate: are
Cross Modern chalk deposits can barely see the sections below ground as
sections colouring very faint
limited in the Isle compared to
other areas.
3D Move Good: Sections do appear to be in the correct place in
model model
Explanation Good: Clearly linked content to course material - could
have mentioned monocline more
Visualisation Good: views above and below ground provided
Presentation Good: labels of strucutre would have helped
