Evaporites and the Environments in Which They Form (March 31 & April 2)

For evaporites, there is nothing quite like a virtual field trip to a sabkha, courtesy of Dr. Wikipedia. The Wikipedia page on evaporites is another good gateway of information and links. I’ve worked with the evaporites in the Purbeck Formation (Jurassic-Cretaceous) of southern England. We can take another virtual field trip to the Great Salt Lake in Utah to see modern evaporites forming. (I was there three years ago and will show plenty of photos in class.) You can also take a short trip to Badwater in Death Valley — the lowest point in North America — where salts of various kinds are forming from evaporation. (The Wooster Geologists visited Death Valley during a Spring Break trip.) The Dead Sea (Israel and Jordan) is a fascinating place for geology, ecology, economics and politics, as you can see in this short video (emphasizing its environmental problems) and this visit by IS student Melissa Torma and me. Did you know that during the Miocene the Mediterranean Sea became a vast evaporative basin? Of course you didn’t — this is why you need me!

Dr. Ian West, who, as we Americans often say, is “very British,” has a comprehensive page of sedimentary geology web resources, including bibliographies. It may be useful for your research paper. If you want to see all the ways to get hurt on a geological field trip, check out his safety page.

Just for your entertainment, here is utter nonsense with a sedimentological basis: “The Artistic Technology of the Ancients: Osijela Hill in the Bosnian Pyramid Complex“. It is a bottomless pit of senseless speculation grounded on complete ignorance of sedimentary structures and stratigraphy.

Your second lecture exam is on Thursday, April 2, and it covers everything we have done through Tuesday, March 31. Here is a copy of the Spring 2019 second Sed Strat test. We’ll figure out a system for you to take this test off campus.
