tom morello dating - Recent radiocarbon dating

Our research takes us all over New Zealand and the world to areas such as southern China, northern Australia, and Southeast Asia.

– If the macrofossils are chosen for the analysis, the reported results will be as “plant material”.

If the sediment is chosen for the analysis, the reported results will be as “bulk organic carbon” or “total acid insoluble organics” depending on the sediment fractions included in the analysis.

– Sediments are complex systems containing carbon of multiple forms, sizes ranges and sources.

Please contact us to discuss the nature of your research objective to ensure the most appropriate pretreatment of your sediment sample.

In general the plant dates are usually more reliable as they typically represent a more unique event in time.

The plants were relatively short-lived as compared to the time it may have taken for the sediment to form.

This is mostly true for sediments that are organic rich (dark black or brown in coloration) as well as for sediments that are not well drained and where water ponds (like swamps, peat bogs, etc).

In areas where there is not much rain fall or the sediment is well drained or is low in carbon (light tan or gray sediments), humic acids may not be much of a problem.

The Waikato Radiocarbon Dating Laboratory is involved in research projects around the globe, which cover a diverse range of radiocarbon dating topics/areas.

Current projects involve researching the history of Arnhem Land ancestral sites in northern Australian, surveying and excavating shell mounds across Cape York Peninsular, studying the high-resolution store of information about past environmental conditions from sub-fossil kauri logs and identifying how Asian civilisations emerged.

Sediment geochemistry is very complex and can change from area to area even over small distances.
