To Start with......

Click on the following web site; read it, take notes, and pay attention to the photographs. You'll have to recognize them again....

Georgia Online web site

Click on the following links and answer the questions below...

Georgia Online sed structures lab

Sketch the drawings on the web site, and visually compare the sketch to the real examples in the photo's.

1. How do symmetrical ripples form?
2. What are sole marks, and how do they form?
3. What are flute marks? How do they form? How can we determine direction of flow using flute marks?

Answer the questions below by going to the following web site...

Sed Structures

Click on "Chemical structures", then on each progressive link to answer the following questions. Anytime you are instructed to "click on" something, click on the small blue arrows.

4. How are stylolites formed?
5. What are concretions, and how are they usually formed?
6. What are crystal casts, and how are they formed?

Click on "Biogenic Structures"
7. What are each of the following: Trace fossils; grazing Trails; burrows.
8. What are stromatolites?
9. Thought question - answer this if you can reason the logic behind it - at least make an attempt! You first must understand how a stromatolite forms, or grows.....

>>>> Why would a stromatolite be good to use as an indicator of which direction was oriented upward?

Click on "Deformational Structures".
10. Draw a flame structure.
11. What is a load cast?

Click on "Current Flow Structures".
12. What are the 3 ways parallel laminations can form?
13. When do ripple marks form?

Go to the following web site and TAKE NOTES! (They MUST be handwritten, and I'll let you use them on the test!)

For this web page, click on the links on the left side of the page for both lecture and lab on sedimentary rock, and read through the material. It will get you ready for the lab tomorrow.

I especially want you to go through the lab material AFTER you read through the lecture material. DO THE LAB!!!

I cannot stress this enough, MAKE SURE YOU TAKE NOTES ON THIS!!!

When you get to this site, click on "Lecture material" in the left margin, then scroll down and click on "Sedimentary Rocks".

When you finish, again look at the links in the left margin. Click on "lab material" then scroll down and click on "Sedimentary Rock Identification", read it, then do the lab.

Sed notes1

You will probably not have time to see this site, and that's OK as long as you complete the site listed above.
The next one may take several attempts at reloading the page, something seems to be going on at JMU.

Sed notes2

It would be a GOOD thing to take a look at the links from both the previous sites, there are links for all three rock types from those pages.
