ANNOUNCEMENTS

WELCOME to Petrology!
I am really looking forward to spending this semester with you, as we explore the science of Petrology and Petrography, expanding on the knowledge that you have already accumulated about rocks and minerals.

As indicated on your syllabus, there is not a specific, required text for this course. However, your success in this class will require that you have (an) appropriate text reference(s) available. In addition to the Earth Materials and/or Mineralogy text that you already have, I will have additional resources available in class. You might also consider acquiring one of the Petrology texts that are listed on your syllabus - the ones that include all 3 main types of rocks are the most appropriate for this class.

I'm looking forward to a great semester with you!

Topics and Activities - "live" version. This page will be regularly updated as needed, and due dates, assignment details, and reading topics
will be linked here for your reference. Check this page regularly to stay current!!

DUE DATE

20 Feb	You should have completed your descriptions and exploration of the igneous rocks, from our original set of 36.
18 Feb	Complete and turn in the packet that was given to you in class on Wed, 13 Feb (mole %, weight %, ternary plots). If you need extra pages from this packet, you may find it here, available for printing.
13 Feb	originally requested that your overview of 36 rocks be done by today! Let's keep working on those!
6 Feb	Bowen article summary: When reading any scientific article, there are some basic aspects that you should be able to consider, and that you should be able to understand, if only in a rudimentary way, about the work that is reported. I have listed some of these below, and want you to start by considering these aspects with respect to a fairly significant geologic report. Read the Bowen article, and submit a brief summary of the following, *in your own words:* 1. List some of the important considerations in this research; that is, what are some of the assumptions, prior work, and basic observations that led to undertaking this particular direction of research. 2. Describe the general types of methods used for this research: what kinds of data were collected, and using what types of methods? 3. Describe the conclusions reached by the author, and briefly comment on how these conclusions are supported by the data. 4. What did you find to be most interesting in this article? 5. What aspects did you find to be confusing/ unclear/ "over your head", or you had difficulty understanding the significance or the relationship of that aspect, to the premise of the research and/or the conclusions that were reached?
