GEOCHEMISTRY 5063:  Tentative Schedule

Fall 2005

 

OBJECTIVE:  That students will gain knowledge and information necessary to estimate/calculate element abundances and distribution within the earth.  The objective requires that students 1) know the cosmic abundance of the elements and the earth’s structure and composition, and 2) understand the factors affecting ionic substitution/sorption and compound equilibria.

PAPERS/PRESENTATIONS

 

The outline of the required course paper must provide enough detail so that the topics and depth of discussion in the paper is clear.  A list of references is to be attached to the outline.  The references should include more than books and especially should include recent journal articles.  The value of the outline is that of an exercise.

 

Papers are typically about 15 pages long (maximum 22 pages).  Turn in two (2) copies of your paper by November 14.  The papers must follow the format of an appropriate journal (indicate the journal), i.e. include an abstract, headings, figures and/or tables, list of references (including up-to-date journal articles).  Papers MUST be resubmitted for a second grading.  The draft is 10 percent and the final version is worth 10 percent.  Papers will be graded on the following basis.

 

            Content                        40%

            Organization                 30%

            Mechanics                    15%

            References                   15%

 

 

Oral presentation of a summary of the pertinent parts of the paper should be timed for about 10 minutes.  The presentations will be graded on the following basis.

 

            Content                        30%

            Organization                 35%

            Oral                             15%

            Visual Aids                   20%

 

 

GRADING

 

The paper will constitute 20% of the course grade and the presentation 10%. Tests and final exam each comprise 20% of your grade.  Exercises 10%.

 

CHEATING and DISRUPTIVE BEHAVIOR:  Questions about academic responsibility, cheating, etc., will be resolved with reference to established University regulations.  For further information about the Code of Student Life go to http://advancement.uark.edu/catalogofstudies/02-03/regs/default.html.  Disruptive behavior is any of the following:    

1.  Speech or action that may be deemed disrespectful, offensive, and/or threatening.

2.  Conduct, speech, or activity that interferes with the learning activities of other students.

 

Disruptive behavior will not be tolerated and disruptive students may be asked to leave the class.  For more information on disruptive behavior check http://www.uark.edu/ua/dosweb/.
