Carbon dating earthquakes


By comparing the different burn rates at various temperatures between two samples, scientists can estimate the age of each sediment layer.Together, the two dating methods allowed scientists to identify increases in the concentration of older organic matter and carbon at three distinct place in the core.This process of decay occurs at a regular rate and can be measured.By comparing the amount of carbon 14 remaining in a sample with a modern standard, we can determine when the organism died, as for example, when a shellfish was collected or a tree cut down.However, there are a number of other factors that can affect the amount of carbon present in a sample and how that information is interpreted by archaeologists.Thus a great deal of care is taken in securing and processing samples and multiple samples are often required if we want to be confident about assigning a date to a site, feature, or artifact (read more about the radiocarbon dating technique at: Shell may succumb to isotopic exchange if it interacts with carbon from percolating ground acids or recrystallization when shell aragonite transforms to calcite and involves the exchange of modern calcite.
