Although I'm not a geologist, I have been collecting minerals for years. My
collection is really ______ because I've traveled all over the world to find
them. Today I've brought a few specimens 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,
______ are the most ______ minerals and are divided into a number of types.
These first samples are ______. Notice that they vary in color from white to
pink to red. This glassy one is found in volcanic rock. In fact, I found it in
New Mexico on a collecting trip. This next sample that I'll pass around is a
______ mineral, also called amazon stone. You can identify it by its bright
green color. It's often used in jewelry and really is quite attractive. These
final samples are all ______ feldspars. Many plagioclases are very rare, so I'm
particularly proud of the variety in my collection. I've also brought a few
______ of some larger mineral samples, and if you'll turn out the light now, I'd
like to show them to you.
