Isotopes of lead

Large submarine landslide, Kitimat Arm, B. Google Scholar Vollenweider, R. In addition, the results of the sensitivity analysis are reported. The sediment Ldad may be supplemented with estimations of the content of alga pigments in the depths required. Thus, it will be possible not only to describe the sediment age, but also to give a picture of the dominant Datiny of plankton alga at the dxting time. Sediment studies Led also Leax supplemented with determinations of e. Method Decay of uranium in the earth's crust releases the gas radon. This gas produces Pb by decay in the atmosphere. In the water phase Pb is adsorbed to particulate matter and together they are deposited in the sediment.

The remaining amount of Pb at a certain depth will reveal the age of the given sediment layer. Documentation includes photographs of the overall object and the sample site, object description and purported age. Conclusion Though more commonly performed on organic materials, lead testing may be used on samples of metal that contain lead. If a metal sample is found to contain the lead isotope it cannot be more than, roughly, years old. This analytical technique is not used to authenticate antiquities but to detect modern reproductions. Notes Lead may exist in detectable quantities for roughly years in organic materials.
