Radiometric dating applied to sedimentary rocks

Absolute dating is necessary for knowing specific time isotope K/Ar in mica, especially in the crystalline rock: igneous and metamorphic rock. There are two main methods determining a fossils age, relative dating and absolute dating.Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.Free 5-day trial Discover how geologists study the layers in sedimentary rock to establish relative age.

The majority of the time fossils are dated using relative dating techniques.

Geologists establish the age of rocks in two ways: numerical dating and relative dating.

Numerical dating determines the actual ages of rocks through the study of radioactive decay.

Your goal is to study the smooth, parallel layers of rock to learn how the land built up over geologic time.

Now imagine that you come upon a formation like this: What do you think of it? How can you make any conclusions about rock layers that make such a crazy arrangement?
