Limitations of the Technique Every scientific method has its limitations.This is because the fundamental assumptions or axioms, on which a method like carbon dating is based, are only approximately true or accurate.It is doubted due to certain perceived flaws in its fundamental assumptions and ambiguous results.

This may lead to an inaccurate determination of age. However, error in determination of age, by carbon dating methods can be compensated by using other dating techniques, which use radioactive elements, other than carbon.This dating technique is inaccurate at times but its error levels are very low and certainly not inaccurate enough to be called wrong.All the physical laws we know have limits of validity.The fact that scientific methods like these, fail beyond a certain domain of approximation, doesn't make them redundant.The possibility of contamination of very ancient samples, is unavoidable.

Contamination disturbs the ratio of carbon isotopes found in situ, in the sample.Because rubidium is concentrated in crustal rocks, the continents have a much higher abundance of the daughter isotope strontium-87 compared with the stable isotopes.This relative abundance is expressed as the Sr ratio, where strontium-86 is chosen to represent the stable isotopes strontium-88, strontium-86, and strontium-84, which occur in constant proportions in natural materials.One reason is the fact that it has a radioactive isotope and second reason is that life is based on carbon compounds.This made age determination of carbonaceous life possible.Thus, a precise measurement of the Sr ratio in a modern volcano can be used to determine age if recycled older crust is present.
