How to identify rocks.

To accurately distinguish gold-bearing rocks and minerals, keep in mind the following: Look at the color, hardness, and geological location. Use a magnifying glass or microscope for closer examination. Perform density, specific gravity, and streak tests in a lab. Be aware of false signals like pyrite or chalcopyrite. When identifying metamorphic rocks, it is common for geologists to focus on specific ‘indicator minerals’ that serve as clues about the degree of metamorphism a rock has undergone. To identify an igneous rock, first identify its texture. Then, perform basic tests on the rock observing its color, hardness, fracture tendency, and acid reaction.
