Geology 1100
Introductory Geology
The lab test will be on Friday, 20 March 2020. Students with last names beginning with the
letters A to Mc will show up, ready to take the lab test, at 3:05 PM.
Student last names beginning with Mi to Z will show up, ready to the take the
lab test, at 3:35 PM.
The lab test will consist of 14 stations. Students will have
1 minute at each station. After all 14 stations have been visited,
students may return to any station, if desired (one at a time, however).
A study set of minerals & igneous rocks & sedimentary
rocks & metamorphic rock will be put on reserve in the library (Warner
Center, OSU-Newark campus).
The complete study
set consists of TWO trays of specimens (see list
below). Each specimen is labeled. Please try not to mix up samples
& labels. I will check on the study sets periodically to ensure that
samples and labels correspond correctly.
Photographs
and descriptions for all 3 groups of rocks that are fair game for lab test
questions are available at my geology
website and my flickr
website - Igneous,Sedimentary, Metamorphic. Common
minerals are here. Labeled photos for the minerals are also here.
Example Lab Test Questions:
Identify this
mineral.
Identify this
rock.
Identify this
rock. Is this rock felsic or mafic?
Identify this
rock. What is the texture of this rock? (options: crystalline, clastic,
foliated, glassy, vesicular/frothy)
Identify this
sedimentary rock. Is it siliciclastic, biogenic, or chemical?
Identify this
mineral. How many different cleavage planes does it have? (options: 0, 1,
2, 3, 4, 6)
Identify the
pink mineral in this rock.
