Lab8 Exercise: Identification of Sedimentary Rocks
In this laboratory exercise, you will identify some common sedimentary rocks based on their texture and composition. Feel free to download the Sedimentary Rocks Photo Guide from the online supplement to help you make your identification.
Instructions
Step 1: Retrieve the bag labeled Lab #7 Sedimentary Rock Samples from your lab kit,
and place the specimens (numbered 11 through 17) on a white sheet of paper.
Step 2: Determine the identity of each rock, then write its name in the proper cell of
Figure 7.7.
The flow chart in Figure 7.8 will help you to narrow down the possibilities.
Feel free to conduct tests you learned in Lesson 5 to help you identify mineral
components. If you decide to conduct an acid test, rinse the sample in water
and dry it first so that you don’t get a false positive result from dust in the bag
that may have settled on the sample.
