and wetter mid-latitude zones to the north.

CONCLUSIONS
REFERENCES
The Triassic succession in the central North Sea
presents a fragmentary record of episodic exten-
sional tectonics, halokinesis and climate change.
Rifting in the late Early Triassic and Late Triassic
can be inferred from regional evidence from adja-
cent basins and subtle indications of thickening
towards the Fennoscandian margin where the
main basin bounding faults were probably located.
Halokinesis was widespread, but this affected
primarily the more mud-prone Early Triassic Smith
Bank Formation and the expansion of major
Skagerrak Formation fluvial systems probably took
place during periods of relative fault quiescence.
Salt movement during these periods does not
appear to have been significant in confining or guid-
ing the fluvial systems, which probably had profiles
which were elevated above the level of subdued salt
movement and which supplied sufficient sediment
to infill any slowly evolving topography. However,
halokinesis was a significant contributor to the local
preservation of stratigraphy through the conveying
of successions below the erosion level of succes-
sive Jurassic unconformities. The apparently sim-
ple Skagerrak Formation succession of alternating
sand-prone and mud-prone members was a product
of fluctuating climatic conditions within the head-
waters of the fluvial drainage. Fluvial expansion
occurred during pluvial events, which increased
runoff from the catchments and extended intermit-
tent discharge streams into the dry basin. During
periods of sustained drought the fluvial systems
contracted as the region reverted to the background
aridity that characterised much of the north-west
European region throughout the Triassic. These
pluvial events appear to have been driven by cli-
matic warming, which intensified the Tethyan
monsoon, enhanced evaporation and weakened the
north-easterly trade winds which normally directed
moisture laden air masses away from the region. In
addition, precipitation from wetter, higher latitude
climate zones may have episodically migrated
southward, leading to a latitudinal belt of sandy,
vegetated fluvial systems to the north of widespread
Keuper and Mercia Mudstone playa.
