Abstract

The numerical procedure of sequence slotting aims to combine, in a mathematically optimal manner, two ordered sequences of stratigraphical data (eg. loss-on-ignition, percentages of different biological taxa) into a single sequence, while preserving the ordering within each sequence and satisfying any other relevant external constraint such as volcanis tephra layers. The procedure provides a convenient means of core correlation in palaeolimnology and is illustrated by two examples. The first involves univariate pollen data from a lake-sediment core being matched with isotopic ice-core data and its associated chronology. The second involves core correlation of two to four cores with a dated master core from eight mountain arctic lakes in Europe using dry weight and bulk organic matter (loss-on-ignition) data as the proxy variables to derive 3405 age estimates for the individual core samples.
