NSCI 1721 (Intro to Geology): Rocks & Minerals

Mindat.org is the world’s leading authority on minerals and their localities, deposits, and mines worldwide.

A basic guide to identifying minerals on hardness, luster, color, streak, specific gravity, cleavage, fracture, and tenacity.

The MN Geological Survey provides an overview of rocks and minerals and links to more detailed information.

Knowledge of the physics and chemistry of the planet’s “bones” is essential to a complete understanding of Earth science. Ranging from the Mohs scale and specific gravity to silicates, carbonates, and halides, this video delves deeply into the composition, properties, and classification of rocks and minerals. An element of forensic-type analysis is also brought into play, since any stony formation represents a portion of the planet’s history and local conditions. A viewable/printable instructor’s guide is available online.
