Daily Objectives #2  (January 11, 2007)                                                                                  Dr. Sanders

By the end of today's class, you should be able to do the following:

* Make a list of the types of projects on which engineering geologists and geotechnical engineers work.

* Respond appropriately to the list of skills in What should you bring to this course?

* List the eight common rock-forming minerals mentioned in your textbook and describe their properties and general chemical composition. 
    (feldspars, quartz, ferromagnesian minerals, iron oxides, calcite, dolomite, mica, and gypsum)

* Describe hand samples of the common rock-forming minerals; give mineral names where appropriate.

* Suggest why some of the specific properties of these minerals might be of importance to a geotechnical engineer.

* Name and give concise definitions of the three major classes of rocks.  For each one, list subgroups and describe their formation and important characteristics. 

* Examining hand samples of various types of rocks, construct reasonable hypotheses as to how they formed; classify them according to your hypotheses.

* Suggest why some of the specific properties of these rocks might be of importance to a geotechnical engineer.

* Describe the importance of discontinuities (bedding planes, schistocity, folds, joints, and fractures in engineering analysis).

* Considering the different goals and purposes of geologists and geotechnical engineers, write definitions of "soil", "sediment", and "rock" that would be suitable for each group.

* Describe the characteristics of six different environments of soil formation mentioned in the textbook.

    (residual, glacial, alluvial, lacustrine, aeolian, and colluvial soils)

* Answer "Questions and Practice Problems", p. 32-33:  Problems 2.1, 2.2, 2.3, 2.4, 2.5, and

"Comprehensive Questions and Practice Problems", p. 45:  Problems 2.13 through 2.19.
