Aggregate is defined as which of the following?

• A. A solid mass of individual, randomly oriented crystals intergrown or held together by a natural bind agent
• B. A single crystal with uniform properties
• C. A shaped stone with flaws
• D. A group of crystals bound by metal

Answer: (A)

An aggregate is a solid mass formed by many individual crystals that grew together and interlock, often held together by a natural binding material. The crystals are typically randomly oriented, so there isn’t a single continuous crystal lattice. This distinguishes aggregates from a single crystal, which would have uniform properties throughout and a definite crystal form. It’s also different from a shaped stone with flaws, which focuses on external imperfections rather than how the material’s internal crystals are arranged. And it’s not describing a group of crystals bound by metal, which would imply a metallic context rather than mineral intergrowth. So the best description captures the intergrowth of many crystals in a random, bonded mass.
