Advance through each of the following slide decks to see one or more photographs of each sample. Some slides also include a short video of the sample being rotated. Videos do not have sound. If you are unable to see the slide decks, click on each sample title to open the slide deck in a new window.






The slides below show three examples of the same general rock type. Describe the example indicated by your TA, however you may find it useful to look at all three examples to get a better idea of the general characteristics of the rock type.
