Radiometric or Absolute Rock Dating
The results are often determined by the estimates of the presumed age of the strata based on relative ages. The age determined by relative dating is based on the rules of super imposition and the presumed age of strata based on fossils. The deeper strata is presumed to be older than strata above. The strata with the simpler fossils is presumed to older than what ares the absolute dating methods with more complex fossils regardless of which is above the other.
