ABOUT THIS REPORT
The end-Permian-Triassic extinction happened over a long
period of increasingly more anoxic conditions,
and the Mesozoic thus began with a much impoverished biosphere. From
the Early Triassic the recovering of species and the evolution of new
The shallow stratigraphic cores taken by IKU in the late 1980's cover
this long period of increasing biodiversity until the next extinction
at the end of the Triassic.
During this time
What was the palaeo-environment in the Nordkapp Basin?
Which sediments were deposited?
Which sedimentary facies from the Early Triassic to
the Late Triassic are present in the Nordkapp Basin today?
How do the cored sections with Triassic sediments
correlate across the basin?
How can a detailed chronostratigraphy be established
for these barren sediments?
Did major tectonic events occur, and if so, when did
How did the sedimentation rates in this area vary
during the Triassic?
How did the accommodation space vary?
How were the recent burial and uplift conditions?
This study, based on IKU's shallow stratigraphic cores from the area
presents answers to these questions.
The report integrates magnetostratigraphy with sequence stratigraphy
and biostratigraphy from Sintefs original reports
updated with the latest biostratigraphy data from Vigran et.al. (in
press) and adjusting and calibrating sequence boundaries and
biostratigraphy with the magnetic polarity zones.
The study was carried out in collaboration with Sintef.
