Correlation of marine and terrestrial Upper Cretaceous sediments by their magnetic susceptibility

Plots of magnetic susceptibility versus depth of sediment samples from both marine and terrestrial series demonstrate that, within a specified time interval constrained by magneto- and biostratigraphy, it is possible to interpret the pattern in terms of orbitally driven sedimentary cycles (Gilbert - or Milankovic cycles) with periodicities of around 100 and 20 Ka respectively. At present the method allows correlation of marine and terrestrial deposits with a time resolution of about 10 Ka. Some peaks have characteristic shapes and interference patterns that may be recognized over wide areas. Sediment series have been studied from central Poland, south Israel, south France, south China and Denmark. December 20th. 1992.
