The Earth is a geological system, and mineralogy serves as a foundation for its study. Minerals are the fundamental building blocks of the Earth. This class provides the basis for your geologic careers. Mineralogy is not only essential to geologists, but to everyone because minerals are also an integral portion of our everyday natural environment.
Minerals compose the Earth and form the
Earth's substrate in which our food grows; they soften our water,
they cleanse hazardous wastes and they provide us with materials
that bring our life above subsistence living such as aluminum,
steel, and plaster board. Consequently, it is imperative that they
be understood and appreciated. Mineralogy is even more important
now as we confront the many worldwide environmental crises e.g.
where to store high-level hazardous wastes - in geologic
repositories, how wastes interact with rocks and minerals, -
where to locate aquifers for vanishing groundwater resources and
the 'asbestos' problem.
Each of us can make a difference when asked to vote on these issues and when discussing these topic with neighbors. In addition, minerals are simply beautiful to observe!
This class has been prepared to provide a foundation for your
future geologic endeavor. Mineralogy is amazing and fun!
grades will be assigned from the final numerical score based on
the performance relative to the rest of the class.
The top 25% of the 10 pt letter grade (A, B, C, D) will get a + grade; the bottom 25% gets a - grade.
Attendance: Mandatory. If you are going to be absent, you must notify Prof. Dutrow ahead of time for an excused absence.
Make up exams: You must notify Dr. Dutrow ahead of time if you are missing a test.
Lecture exams will be 5 essay questions; Lab exams will be 10 questions. You may only miss one test and take a makeup.
Makeup quizzes: None will be given.
Cell Phones: No cell phone use is permitted during class. If you use your cell phone, you will be asked to leave class.
Class is a concentrated study time, if you are on your phone, you are distracted.
During lab, you must ask permission to use the cell phone for photography of minerals through the microscope
Example lecture tests are posted on the web; self-assessment questions are posted for EACH lecture.
These tests and questions provide a study guide.
You are responsible for all material covered in class and assigned as reading material
Labs are due at the due date as given in class.
For each day late, 5 points will be deducted from your score until the labs are returned. After that date, a zero is assigned.
If you are going to miss lab, you must notify Prof. Dutrow prior to class time.
Here are some helpful hints to make Mineralogy easier and more fun!
