Statement

: In 1993, a series of overlapping sedimentary cores were recovered from the centre of the Marcacocha basin using a 5 cm diameter Livingstone corer. The overall composite length of the sequence was 8.25m, consisting of an upper 50cm horizon of dense peat, underlain by a series of highly organic lake muds (with occasional relatively fine-grained inorganic horizons) to a depth of 6.3m; sediments below this level consisted solely of gravels. The uppermost peats were too fibrous to core, so were sub-sampled continuously from a hand-dug pit at 4cm intervals. A chronology for the sequence was developed using a combination of seven 210-Pb determinations (applying the Constant Rate of Supply model) and six radiocarbon dates from bulk organic carbon (five conventional dates and one AMS), demonstrating that the sequence extended back continuously for the past ca. 4200 years.
