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 you with just one previous geology course. You can always practice your stratigraphic skills with this elaborate dating assignment you can download and then cut into little cards. (I wouldn’t bother, but maybe you have a roommate with little to do?) Visit Jurassic Tank, an experimental stratigraphy apparatus at the University of Minnesota. This detailed website on the geology of the south-central coast of England is also a very good example of stratigraphy in action (and where I had many students doing fieldwork years ago). For the lab, you can’t beat these brief descriptions and images of sedimentary structures from Wikipedia.

Here is your Essay #1 assignment.

Geology in the News –

Earth’s oldest rock was apparently found on the Moon by Apollo 14 astronauts. It is about 4.1 billion years old and was blasted off the Earth by a giant impact. You know there’s a good story here.

The famous 79 CE eruption of Mount Vesuvius apparently turned an unfortunate man’s brain to glass. I can’t tell exactly how this happened, but there is a skull with a supposedly vitrified brain. Obsidian, I suppose.
