Radiocarbon dating is only accurate for objects no more than


Different dating techniques should consistently agree

One of the advantages of fission track dating is that it has an enormous dating range. After 5,730 years, about one-half of the carbon-14 atoms will have decayed.

C, or radiocarbon. That you must have a verifiable amount of the substance being measured in the beginning when the rocks were formed. By measuring the light emitted, the time that has passed since the artifact was heated can be determined. Radioactive decay refers to the process in which a radioactive form of an element is converted into a nonradioactive product at a regular rate.

Relative dating methods tell only if one sample is older or younger than another sample; absolute dating methods provide a date in years. Correlation of strata are well understood on a global scale.

What is archaeology?

In a given time period. The fission fragments have a lot of energy, and they plow through the rock, leaving a track that can be made visible by treating the rock. Really just beyond the c14 limit for sites such as these. Radiation entering the atmosphere back then and less c-14 would have been produced.
