Introductory Geology

 

Lab Test

 

The lab test will be on Friday, 22 March 2019.  It 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).

 

Students with last names beginning with the letters A to K will show up, ready to take the lab test, at 8:00 AM.  Student last names beginning with M to Z will show up, ready to the take the lab test, at 8:30 AM.

 

A study set of minerals & igneous rocks & sedimentary rocks & metamorphic rock is 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, MetamorphicCommon minerals are here.  Labeled photos for the minerals are also here.

 

 


 

 

 

Example Lab Test Questions:

Identify this mineral.
