Minerals and Rocks in the Environment – EPSc 336  (Spring 2017)

 

Course Description:  This is a combined rock and mineral course with focus on environmental issues and applications. We will introduce and discuss mineralogic and petrologic concepts relevant to environmental geoscience pursuits.  The course will provide fundamentals of mineralogy and crystallography, key mineral groups, and foundations of igneous, sedimentary, and metamorphic rock systems. We will address the mineralogy of environmental systems such as soils, marine environments, aerosols, mines, and radioactive wastes. The course will also provide an overview and lab demo of analysis methods used for environmental geoscience applications.  We will attempt to plan a full-day field trip for one day in early April.

 

Note for EES students: This course or Earth Materials (EPS 352) is one of the requirements for EES majors and is one of the possible electives for minors.  Please note that only one or the other (336 or 352) can be taken for credit toward the major/minor.  EPSc 336 is designed at a more introductory level than Environmental Mineralogy (EPS 430).  For those students intending to take EPS 430, Earth Materials (EPS 352) is prerequisite.

 

Pre-requisites: EPSc 201 Earth and the Environment, Chem 111A or AP Chem score of 4; or permission of instructor.

 

Class time: Two 1.5-hour class periods per week with several of the regularly scheduled class periods spent doing labs (mineral and rock identification, analysis methods).  Class will be divided between lecture, lab, and case studies involving environmental issues.

 

Main Textbook: Earth Materials, Hefferan and O’Brien, 2010

 

Supplemental materials: We will use a course pack that draws upon recent, relevant issues primarily using articles from the journal “Elements” supplemented by extracts from the following books: Environmental Mineralogy, Mineralogical Society Series, 2000; Environmental Mineralogy II (Vaughan and Wogelius, Ed.) EMU Notes in Mineralogy 13, 2013; Soil Mineralogy with Environmental Applications, SSSA Book Series 7 (Dixon and Shulze, Ed.), 2002; Minerals, Their Constitution and Origin, Wenk and Bulakh, 2004; and Geology and the Environment, Pipkin & Trent.

 

Term Project/Case Study: Topic to be agreed upon by student and professor.  Students will research a specific topic and write a short (~10 page) paper, to be presented in class during the semester.

Grading:

Exams: 3, 15% each

Homework Assignments: 25%  (~ 5 assignments, 5% each)

Term Project: 15% 

 In class brief: 5%

Class Participation: 10%
