The illite layers are bonded by potassium ions. The negative charge to balance the potassium ions comes from the substitution of aluminum for some silicon in the tetrahedral sheets. 11 Atomic structure of montmorillonite (After Grim, 1959. 12 Diagram of the structures of (a) kaolinite; (b) illite; (c) montmorillonite isomorphous substitution. Illite particles generally have lateral dimensions ranging from 1000 to 5000 Å and thicknesses from 50 to 500 Å. The specific surface of the particles is about 80 m2/g.

2 Å thick. The layers are held together by hydrogen bonding. Kaolinite occurs as platelets, each with a lateral dimension of 1000 to 20,000 Å and a thickness of 100 to 1000 Å. The surface area of the kaolinite particles per unit mass is about 15 m2/g. The surface area per unit mass is defined as specific surface. 13 shows a scanning electron micrograph of a kaolinite specimen. 12b). It is sometimes called clay mica. The illite layers are bonded by potassium ions. The negative charge to balance the potassium ions comes from the substitution of aluminum for some silicon in the tetrahedral sheets.

Thus, depending on the proportions of minerals available, different types of igneous rock are formed. Granite, gabbro, and basalt are some of the common types of igneous rock generally encountered in the field. 2 shows the general composition of some igneous rocks. 3 Scanning electron micrograph of fractured surface of quartz showing glass-like fractures with no discrete planar surface (Courtesy of David J. 4 Scanning electron micrograph showing basal cleavage of individual mica grains (Courtesy of David J.
