     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 on which you will build the remaining of 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 crack hydrocarbons, they cleanse hazardous wastes and they provide us with materials that bring our life above subsistence living. 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 hazardous wastes - in geologic respositories, how wastes interact with rocks and minerals, and where to locate aquifers for vanishing groundwater resources. 

    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 with you in mind and to assist you on your future geologic endeavor. Our efforts into this course are considerable, we expect the same of you. Most of all, we love minerals and mineralogy and  hope you will too.


Enjoy !!!!!

Grading procedures:

  1. The grades will be based on performance on a combination of lab and homework exercises, three lecture exams, three lab exams, final exams and in class quizzes and attendance.
  2. For group labs, a score will be given to the group; i.e. all members of that group will receive the same score for that project.
  3. The breakdown of weighting of scores are:

            Letter grades will be assigned from the final numerical score based on the performance relative to the rest of the class.

Class Policies:
            Attendance: Mandatory.
If you are going to be absent, you must notify the professor ahead of time for an excused absence.
            Make up exams:
Lecture exams will be 5 essay questions; Lab exams will be 10 questions.
            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.
                During lab, you must ask permission to use the cell phone (for photography or searching)
             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.

This class requires that you learn to speak the language of the discipline, therefore you must memorize a certain amount of fundamental material, comprehend this material to understand conceptual information,  learn to visualize information in 3D, and combine this information to understand how minerals, and the Earth, work.

Here are some helpful hints to make Mineralogy easier and more fun!

  1. Review and Know Introductory Material in Physical Geology and Chemistry
    Class requires that you have a full knowledge of the rocks and minerals section of your Introductory Geology text. Reread that material. You must also have a working knowledge of introductory Chemistry, especially  elements and the periodic table. 
  2. Attend class
    You are required to attend class. Lecture material is derived from sources in addition to the book. To get an excused absence, you need to inform Dr. Dutrow prior to class if you are going to be absent from class and get the notes from a friend.

  3. Lab
    You are required to attend lab and to remain in lab the entire 1.5 hrs each session. During this time, there is always someone available to help and answer questions! Lab assignments reinforce lecture material and aid in comprehension. They should be thoroughly understood.

  4. Syllabus - Read what is listed.
    The syllabus is available on the web. Refer to it for any updates to material and follow the reading assignments.

  5. Tests and Self-assessment Questions
    Old tests are posted on the website so that all of you have access to previous tests. Working through these tests is a terrific study guide and will help you tremendously in the course. They help you know how I test. Self-assessment questions are posted to reinforce important concepts for each lecture.

  6. TAs and Professor
    If you have questions, take advantage of the T.A.s and the Professor. Feel free to make an appointment to see the professor, the TA or come during office hours.

  7. Enjoy the material!
  8. Occasionally there will be a lecture during lab time and lab during lecture. Reading assignments should be completed prior to the class period as they serve as supplemental material. Bring your questions to class.

 Students with disabilities: Louisiana State University is committed to providing reasonable accommodations for all persons with disabilities. The syllabus is available in alternate formats upon request. If you are seeking classroom accommodations under the Americans with Disabilities Act, you are required to register with the Disability Services (DS). DS is located in 115 Johnston Hall. Phone is 225/ 578-5919. To receive academic accommodations for this class, please obtain the proper DS forms and meet with me at the beginning of the semester.

Code of Student Conduct: Louisiana State University is an interactive community in which students, faculty, and staff together strive to pursue truth, advance learning, and uphold the highest standards of performance in an academic and social environment. It is a community that fosters individual development and the creation of bonds that transcend the time spent within its gates.  To demonstrate my pride in LSU, as a member of its community, I will:

  1. accept responsibility for my actions;
  2. hold myself and others to the highest standards of academic, personal, and social integrity;
  3. practice justice, equality, and compassion in human relations;
  4. respect the dignity of all persons and accept individual differences;
  5. respect the environment and the rights and property of others and the University;
  6. contribute positively to the life of the campus and surrounding community;
  7.  and use my LSU experience to be an active citizen in an international and interdependent world.

The continued success of LSU depends on the faithful commitment by each community member to these, our basic principles.

There are two areas that we will be particularly alert for in this class:


(1) Plagiarism is an extremely serious violation of academic integrity. The Code of Student Conduct defines plagiarism as “the unacknowledged inclusion, in work submitted for credit, of someone else’s words, ideas, or data.” (8.1-C.6)  


Plagiarism can occur in a myriad of forms and media.


Although most commonly associated with writing, all types of scholarly work, including computer code, music, scientific data and analysis, and electronic publications can be plagiarized. The aim of this section is to help students and faculty deal with the complex and important issue of plagiarism on campus.


(2) Copying - Copying from another student's test paper or assignment.

Alcohol Policy (PS-67 Illegal Use of Drugs and Alcohol Misuse): Louisiana State University is committed to maintaining an environment which supports the research, teaching, and service mission of the University. Although the University respects an employee's right to privacy, the illegal use of drugs or alcohol within the University community interferes with the accomplishment of the University's mission.  Louisiana State Law prohibits the consumption, possession, distribution, possession with intent to distribute, or manufacture of drugs described as controlled dangerous substances in the Louisiana Revised Statutes 40:964; and other statutes define the illegal possession and/or use of alcohol.  As such, the Department has reaffirmed the University policy of alcohol-free and drug-free environment on University property at all times and in areas and at times and locations where an assembly of students and faculty would be viewed as representative of LSU (field trips and field camp property as both represent LSU).
