Geology 103 (Sedimentology and Stratigraphy)

 

California State University, Sacramento

 

Week 8:

 

Coal and carbonaceous deposits

and

Alluvial fans

Objectives:

Upon completion of this unit students should be able to:

  • List and describe the properties of different grades of coal in hand specimen

  • List and describe the geochemical properties of different ranks of coal

  • Discuss the abundance of different types of coal in the world and in the United States

  • Evaluate the environmental issues with burning a particular type of coal.

  • Describe longitudinal and lateral profiles (shapes) of an alluvial fan.

  • Discuss the difference between a debris flow and a stream-dominated alluvial fan.

  • List common features and deposits of an alluvial fan, including grain size patterns (longitudinal and vertical).

  • Name the parts of an alluvial fan, and discuss the sedimentary structures in each.

Lab this week-

 

Sedimentary petrography week 2.  We will meet in Placer Hall rm. 1002, and finish looking at clastic sediments in thin section.

 

Your lab write up will be due after spring break.  In today's lab period you will look at examples of the remaining clastic grains.  Your lab will be due the week after Spring break.

 

Bring drawing pencils and colored pencils to lab!

 

I will pass out a copy of the lab.  If you need to print more pages you can get a new copy here:
