Describe the process of relative dating

These techniques can be grouped as numerical, relative dating, and correlation.Numerical techniques are best, but datable materials are often lacking, and in these cases age estimation must be made using relative-dating or correlation techniques.Geologic studies of active tectonism are greatly aided by definition and time calibration of local stratigraphic sequences.Because all dating techniques may be subject to considerable error, reliability should be assessed by stratigraphic consistency between results of different dating methods or of the same method.Bones are primarily composed of the mineral calcium hydroxy apatite.

Correlation techniques are locally useful and depend on recognition of an event whose age is known, such as a volcanic eruption or a paleomagnetic reversal.This chapter is an introduction to rocks and minerals, and the rock cycle.Basic chemistry is important to all sciences, especially geology!In fact, until the eighteenth century, it was commonly believed that the Earth was no older than a few thousand, or at most, million, years old.Scientific detective work and modern radiometric technology have only recently unlocked the clues that reveal the ancient age of our planet.Adequate age control is thus a limiting factor in studies of active tectonism.
