Melissa graduated from NC State University with a Bachelor's Degree in geology in and currently works as a geotechnical lab technician. Figuring out the geologic history of an area seems like a daunting task, but there are several strategies that geologists use to figure out which rocks are older than other rocks, and what geologic processes occurred in a particular order. Geologists can numerically date certain rocks by using the radioactive decay of elements trapped in rocks or minerals to figure out their exact age. However, these radioactive isotopes aren't always present in a rock, so geologists must use context clues to build a calendar called a geologic timescale of when each rock layer in a formation was created. Relative dating uses a series of 5 principles listed in the following paragraphs that help geologists compare the ages of different layers of rock and create a geologic timescale for an area. Most sediments that you see in rock formations are deposited in horizontal layers originally, due to the effect of gravity. If the layers you see are no longer horizontal, the layers were probably affected by an event of some kind after they formed.

Answer Save. Two examples of relative dating: 1. Some fossils, called index fossils, are particularly useful in correlating rocks.

assured, that

For a fossil to be a good index fossil, it needs to have lived during one specific time period, be easy to identify and have been abundant and found in many places. For example, ammonites lived in the Mesozoic era.

Relative Dating

If you find ammonites in a rock in the South Island and also in a rock in the North Island, you can say that both rocks are Mesozoic. Different species of ammonites lived at different times within the Mesozoic, so identifying a fossil species can help narrow down when a rock was formed.

Correlation can involve matching an undated rock with a dated one at another location. Suppose you find a fossil at one place that cannot be dated using absolute methods.

That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age. Some of the most useful fossils for dating purposes are very small ones.
