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 … Continue reading

Continental Margins and Deep Marine Systems (March 24 & 26)

Our Spring Break coincided with a crisis point in global history. The COVID-19 pandemic has changed everything we’re doing. This course, like all Wooster courses and, for that matter, all college courses in the country, is going online only. We … Continue reading

Carbonate Systems (March 3 & 5)

Carbonate sediments are gifts of the sea, so let’s go there first. Maybe you’d like to stay in this nice little resort in Belize? NOAA has a wonderful website called “The Coral Kingdom” with many online photographs of reef animals … Continue reading

Carbonate Petrology (February 25 & 27)

It is with carbonate rocks that we see most distinctly that life is a geological process (trademarked, all rights reserved). The large majority of carbonate sediments are directly derived from living systems, and as such they are excellent indicators of … Continue reading

Coastal & Shallow Sea Systems (February 18 & 20)

The USGS Coastal and Marine Geology Program maintains an extensive set of webpages. One of the most interesting for coastal geology covers the coastal damage produced by Hurricane Katrina in 2005, including impressive lidar images of pre- and post-hurricane coastal … Continue reading

Deltaic and Estuarine Systems (February 11 & 13)

With deltas and estuaries we can apply all those principles of aquatic sedimentation we have learned, and add a few more. The Danube Delta looks like an interesting place to visit, even if it is under siege from pollution and … Continue reading

Terrestrial Sedimentary Systems (February 4 & 6)

This week we continue our discussion of the sedimentology of desert systems. (You’ll have to just endure my enthusiasm for deserts.) To fully sample my joy, I simply must link you to the Wooster Geologists blog entries for our field … Continue reading

Principles of Stratigraphy — Introduction (January 28 & 30)

It is difficult to construct an interesting page on stratigraphy. So many lecture outlines, so few useful pages. The Geology and Geological Time page of the University of California, Berkeley, is not bad as an introduction, especially for those of … Continue reading

Sediments and Sedimentary Processes II (January 21 & 23)

How can I make sedimentary dynamics, at least the statistical parts, interesting? The Web doesn’t help much. We could learn a bit about Sir George Gabriel Stokes (1819-1903) of Stokes’ Law. Most of the web material, though, consists of calculating … Continue reading
