Abstract/Summary

The Turonian-Campanian Upper Chalk in the area between Dorchester and Weymouth in Dorset shows an abnormal development of hard chalk beds in the late Coniacian-Santonian Micraster coranguinum to the early Campanian Gonioteuthis quadrata zones. The chalk is also strongly affected by faults representing the surface expression of reactivated underlying pre-Albian structures. This suggests a link between tectonism and Turonian-Campanian chalk deposition, which may be related to the proximity of the south Dorset disturbance.
