Relative and Absolute Ages in Geology In this lab-learning exercise you will: Use the theory of radioactive isotope decay to calculate parent and daughter isotope abundances and determine the absolute age of geological materials. Determine relative geologic age sequences using the basic principles of relative age determination.

Distinguish different types of unconformities in the stratigraphy of the Grand Canyon. There are two parts to this lab exercise A. Part 1 is on absolute age determinations using radioactive isotopes and their daughter products in geological materials.

In Part 2 you will use the principles of relative dating to determine sequences of geological events as indicated by the layers and structures in the rocks. Part 2 ends with an application of the principles of relative dating to the rocks of the Grand Canyon. E-mail a copy of your certificate to the Assignments folder in the virtual classroom, or else mail in a hard copy, or both.

Carbon decays to Nitrogen with a half-life of 5, years. With such a geologically short half life, carbon can only be used to determine ages of relatively young materials, less than 70, years old. Older materials have so little carbon left that it cannot be accurately measured.

Thus, carbon is of no use in determining the absolute ages of, for example, dinosaur fossils. The only materials that start out with usable amounts of carbon in them are carbon-bearing materials which derived their carbon immediately from the atmosphere or from shallow water. This means that the remains of living things are useful for carbon dating. Most rocks, however, are not useful for carbon dating either not enough carbon, or didn't derive its carbon from the atmosphere-shallow water reservoir.

View the above image, a cross-section side-view of a cut-out through the crust of the Grand Canyon. Study this diagram carefully, noting the orientation of individual rock layers, as well as the type of rock in each layer, and the age of the rock in each layer. Refer to the geologic time scale on page for the names of each of the geologic time periods, as well as the absolute dates attached to each Period.

In order to answer the following questions, you will need additional geologic information about the Grand Canyon. Four major unconformities are evident in the Grand Canyon cross-section. Remember that unconformities represent sections of missing time, either through non-deposition of rocks for a period of time, or through an interval of erosion which has removed some strata.

Strata are layers of rock. The three different types of unconformities are shown in the textbook refer to the index of the book to find where. Each of the four major unconformities in the Grand Canyon can be identified as one of the three specific types of unconformities. For each of the four major unconformities in the Grand Canyon, answer each of the following questions: For the oldest unconformity: Between which two rock layers use the names of the rock layers shown on the diagram does the unconformity occur?

What evidence do you specifically see that allowed you to identify an unconformity at this location? Schist forms deep in the crust and must be uplifted and eroded to have the sediments that form limestone deposited on top. Which of the three types of unconformities is this? It is a nonconformity. In the sequence of geological eons, eras, or periods, where is the unconformity located? Be as specific as you can, such as "between the Jurassic and Tertiary periods," or "Within the Triassic period.

For the next-to-oldest unconformity: Note that the first four answers are already given to you. Enter your answers into the Lab 3B. Remember to do so by the end of the Week, and click "Submit" when you are done.
