Example of absolute dating geology

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

We could assume that this igneous intrusion must have happened after the formation of the strata.In this lesson, we'll learn a few basic principles of stratigraphic succession and see whether we can find relative dates for those strange strata we found in the Grand Canyon.In order to establish relative dates, geologists must make an initial assumption about the way rock strata are formed. sediments, which are deposited and compacted in one place over time.How do we use the Law of Superposition to establish relative dates?Let's look at these rock strata here: We have five layers total.Inclusions are always older than the sedimentary rock within which they are found.
