Aggregate

 

in mineralogy and petrography, an accumulation and accretion of fragments of one or several minerals of varying shapes and structures. Aggregates are classified as cemented, friable, earthy, porous, or dense. According to the shape of the grain, they are called grainy, crystalline, needle-shaped, cubic, fibrous, tangled fibrous, radial, uniform crystalline, shell-shaped, accumulative, and so on; and according to composition, simple—consisting of a single mineral (for example, quartzite, which consists of quartz, and marble, which consists of calcite)—and complex, consisting of several minerals (for example, granite is an aggregate of quartz, feldspar, and mica).
