Many times peat is composed of unrecognizable decayed plant remains that are essentially a mix of everything that was deposited and then decayed in place or a mix of silty peat with some fibrous materials.Sometimes these mold, mildew and fungus get there carbon solely from: (1) the organic substances in the cores (2) from the atmosphere only, and (3) from both the organic substances in the core and the CO2 in the atmosphere.In situations 2 & 3, the radiocarbon ages can be biased in the more recent direction by some unknown amount.Whenever possible, it is best to extract out unique plant remains that you know were deposited in situ and send them for radiocarbon dating.If this is not possible or practical, you may send the bulk sample and we will sieve and extract all the various fractions present and pretreat them.
