Essentially, the paper is composed of seven parts, each of which concerns a group of related nonmetallic minerals such as ceramic materials, gemstones, or abrasives. Following the data pertaining to the minerals of each group are index mars locating the major mineral deposits which are known to date. Production and reserve figures are listed by tables in cases where such information is available
