(woman) I'd like to begin by thanking Dr. Kane for inviting 1 me to be here today. Although I'm not a geologist 2, I have been collecting minerals for years. My collection is rally diverse because I've traveled all over the world to find them. Today I've brought a few specimens 3 for you to see. After I discuss each one, I'll pass it around so that you can look at it more closely.

As you know, feldspars are the most abundant minerals and are divided into a number of types. These first samples are orthoclases. Notice that they vary in color from white to pink to red. This glassy one is found in volcanic 4 rock --- in fact, I found it in New Mexico on a collecting trip.

This next sample that I'll pass around is a microcline mineral --- also called amazonstone. You can identify it by its bright green color. It's often used in jewelry 5 and really is quite attractive.

These final samples are all plagioclase feldspars. Many plagioclases are very rare, so I'm particularly proud of the variety in my collection.

I've also brought a few slides of some large mineral samples, and if you'll turn out the light now, I'd like to show them to you.
