Exercise 11C

The Superior area has a well-exposed sequence of rocks, which nicely represents the geologic history of southern Arizona. The area also contains a number of faults, mineral deposits, and other geologic features.

The photographs in the "Hand sample" column below show rock samples for important rock units in the Superior area. The "Field, close up" column shows close ups of the rock samples in the field. These may help you identify the rock type, by showing the larger context of the sample (layers or not, etc.). The photographs in the "Field, middle distance" column show a middle distance photograph of the sample location to provide you with a perspective of what kinds of landscapes that rock type forms.

Use your descriptions of the sedimentary, igneous, and metamorphic reference suites (Modules 4, 5, and 6) and the rock identification tables in Appendix E in your lab manual to assign a name to each sample.

After you have assigned names to each rock sample, complete Assessment 11C-1 on Canvas.

The links below lead to geologic maps of the Superior Mining Area, Arizona.

Follow the directions in your lab manual to determine the formation name for each rock sample above. Additionally, use the geologic map to answer the questions in Worksheet 11C-3 in your lab manual and then complete Assessment 11C-3 on Canvas.
