Physical properties

Formation & geological history

These specimens represent different minerals and rocks formed through processes such as magma crystallization, hydrothermal activity, and sedimentary or metamorphic alteration, spanning many geological ages and environments.

Uses & applications

Educational identification and collecting; some represented materials are used in jewelry, pigments, abrasives, and construction.

Geological facts

The labels identify a broad assortment, including amethyst, banded agate, blue aragonite, bauxite, carnelian, chalcedony, dolomite, fluorite, malachite, pyrite, and tourmaline.

Field identification & locations

Identify each piece by its label and confirm with diagnostic properties such as hardness, streak, cleavage, and acid reaction; the small size and display lighting limit visual identification.
