Garnet is a dense and hard silicate mineral which occurs in many rock types but it is especially common in some metamorphic rocks like schist and amphibolite. It is a common rock-forming mineral in some igneous rocks. Crystals are usually reddish and isometric. These almandine grains are picked from a beach sand.

Granite and basalt make up the majority of igneous rocks. Basalt is dark and fine-grained with minerals rich in magnesium and iron. It is either extrusive or intrusive and is the primary rock on the ocean floor. Granite is light and coarse-grained and rich in feldspar and quart.
In paramagnetic substances a magnetic field results in a magnetic moment that has the same direction as the applied field Figure 10.1.Paramagnetic substances therefore have positive susceptibilities that extend over a range between 10 4 and 10 2 SI for the common rock-forming minerals Tarling and Hrouda 1993.
