Pairs of neighbouring short columns of peat from two sites in Northern England were divided into contiguous 1 cm thick slices that were sub-sampled for pollen and plant macro fossil analysis.For each slice the remaining peat was then split into humic acid, humin and fulvic acid fractions and radiocarbon dated.This research demonstrates that significant variations can occur in the radiocarbon content of discrete chemically defined fractions of peat. The results from the four columns of peat are highly variable and mutually inconsistent.The fulvic acid fraction, although normally younger than the corresponding humic acid and humin fractions, has very little effect on a combined date in these samples.

Initially, plant macrofossils were used for dating.
