Important Non Silicate Minerals
Although non silicates make up only about 8 percent of Earths crust, some minerals, such as gypsum, calcite, and halite, are major constituents in sedimentary rocks. Furthermore, many others are important economically. Table 2.1 lists some of the non silicate mineral classes and a few examples of each. Some of the most common non silicate minerals belong to one of three classes of minerals-the carbonates
