It is the most helpful book I've ever had for this subject- very clear, and concise but highly informative.

If you are a first time user, remember before you push and add button, [THINK] about who you are actually buying from. If it`a Amazon and you make a mistake or change your mind they will let you delete the order automatically. If your order is from another company then you`ll have to write an e-mail to that company to cancel or change your decision. However, Amazon gives you all the info to do this, so don`t get upset like I did. They`ll take care of you!

This new edition seems to be both a step forwards and a step backwards, at the same time. The list of terms that are explained is exhaustive. In that sense it is an improvement on the earlier edition. Many geographic terms that are relevant to geology have been included for the first time. However, all the diagrams have been omitted (due to space / price constraints?), and if a picture can paint a thousand words...... Overall though an essential text for any student of geology worth their (rock) salt!!
