The assessment of 210Pb data from sites with varying sediment accumulation rates

摘要: The last few years have seen a dramatic growth in the use of 210Pb sediment dating. Despite this, considerable doubt still surrounds nature processes by which is deposited lake sediments, and this has lead to situation where there choice dating models offering different interpretations data. In assessing data it therefore essential first all determine whether consistent with assumptions model, then compare chronology independent evidence. We tested from wide variety sites, our calculations indicate that crs (constant rate supply) model provides reasonably accurate when total contents cores neighbouring locations are comparable.
