Calculating a statistically robust δ13C and δ15N offset for charred cereal and pulse seeds

Abstract:

This study measured δ13C and δ15N of fresh and charred seeds from six different taxa of cereals and pulses. For each taxon, 12 different batches of seeds, all from the same growing context or field, were charred for 4, 8, or 24 hours at 215, 230, 245, or 260°C, with the thirteenth batch left uncharred. The least charred samples showed no average offset compared to their uncharred counterparts, but among the charred seeds, every 15°C increase resulted in an increase in δ15N by 0.12‰, while inc...
