Description

Uh, no. Rocks and minerals are not the same. Check out the twenty rocks and minerals on a 4 x 6 display card with facts about the rocks and minerals printed on the back of the card.

To a casual observer, a rock and a mineral appear to be very much alike.  However, to a geologist, a rock is something much different from a mineral.  A mineral is a combination of two or more elements, while a rock is a combination of two or more minerals.  This reference card is great for learning about the appearance of various rocks and minerals. Attached to a 4″ x 6″ laminated card are samples of twenty common rocks found in the United States: Quartz, Amazon Stone, Epidote, Andesite, Fluorite, Obsidian, Orthoclase, Talc, Jasper, Ulexite, Pyrite, Migmatite, Opal, Chrysocolla, Sulfur, Coal, Dolomite, Magnetite, Calcite, and Terra Cotta. Each sample is about .5″ wide. The back of the card has a very brief explanation about rock classification.
