Advanced General Geology W4001x

Advanced General Geology is an introductory class designed for students who have some science background . This course is a fast-paced one that not only servers to introduce the student to basic introductory material, but also introduces the student to current research topics in the Earth sciences. This is done, in part, by assigning readings in research articles dealing with recent advances in diverse fields while at the same time presenting introductory material.

There is a laboratory designed to introduce students to rocks and rock forming minerals run in conjunction with the lecture. There are at least two required day-long field trips. The required text are: Earth by Press and Siever and The Inaccessible Earth by Brown and Mussett (this text is out of print so copies can be obtained from your TA). There will also be a large number of supplemental readings and handouts given at the beginning of lectures.
