Which of the following could not be dated using radiocarbon dating techniques
The ash itself cannot be carbon dated, but carbon dating can be used indirectly using plants and trees buried by the ash. Other methods such as potassium-argon dating are used for the ash itself. Radioactive dating is only useful in dating igneous and metamorphic rock. Organic material that has not fossilized and does not exceed 70, years of age can be dated by Carbon dating techniques.
9. which item would be dated using radiocarbon dating - footing: man
One of the isotopes, carbon, is unstable. Living things incorporate carbon carbon, carbon and carbon into their cells until they die. At death, no new carbon is added to the cells, but the radioactive carbon continues to undergo nuclear decay radioactive decay so overtime the amount of carbon in the cells decreases. Radiocarbon dating compares the present ratio of carbon to carbon to determine how long ago the living thing died.

Not all materials can be radiocarbon dated. Most, if not all, organic compounds can be dated. Some inorganic matter, like a shell's aragonite fraction, can also be dated for as long as their formation involved assimilation of carbon 14 in equilibrium with the atmosphere. Radiocarbon dating does not provide useful information on materials with no carbon 14 like coal.
