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.
Example include carbon14-nitrogen, uranium-led, uranium-thorium. Relative dating instead allows for identifying the sequential order of geological events one relative to the other.
This is based on the concept that, in a normal depositionary sequence, the deepest layers are also the oldest.
The calculation are based on the percentages of parent, and daughter elements.
The strata with the simpler fossils is presumed to older than strata with more complex fossils regardless of which is above the other.
Absolute dating is based on radioactive decay half lives.
All radioactive substances are found in igneous rocks ( except Carbon 14 which is only used to date fossils less than 50,000 years old).
Volcanoes other fossils can t tell the main difference between relative and extinct. What is the difference between relative and absolute dating methods .
What is the difference between relative and absolute dating of rocks and fossils . This gives away the true age of the fossil that contains c-14 that starts decaying after the.
