An aggregate of one or more minerals, (such as granite, shale, marble) or a body of undifferentiated mineral matter, (such as obsidian) or a solid organic material, (such as coal). Rocks fall into three broadly defined groups: igneous, sedimentary, and metamorphic rocks.
The cornerstone of mineral classification lies in chemical composition. Minerals are defined as naturally occurring, inorganic, crystalline substances with a specific chemical formula and a defined atomic arrangement.
This Mineral Names Dictionary contains mineral names that the average mineral collector will encounter while collecting minerals, attending shows and visiting museum displays. In addition to the most common min‐ eral names, there are some unofficial names which you will still find on labels.
Minerals are materials that meet five requirements. They are: 1) naturally occurring, 2) inorganic, 3) solids, 4) with a definite chemical composition, and, 5) an ordered internal structure.
