These rocks are metamorphic, fine- to medium-grained, and can range in color from dark gray to rusty red. In Wisconsin, the most important iron-bearing minerals are magnetite, hematite, and goethite/limonite. Magnetite is highly magnetic; hold a strong magnet up to a rock to test whether it contains magnetite.

Garnet - Mineral, Crystals, Rocks: The rock-forming garnets are most common in metamorphic rocks. A few occur in igneous rocks, especially granites and granitic pegmatites. Garnets derived from such rocks occur sporadically in clastic sediments and sedimentary rocks. Typical occurrences of the common rock-forming garnets are given in the Table. Garnets commonly contain many inclusions—i.e ...
