  • Aggregates: Mineral information, data and localities.

    Aggregate is a broad classification of coarse to medium-grained rock material intended for use in construction. This can include sand, gravel, crushed stone and mine waste, and rocks of all types can be mined or quarried for aggregate - making use of what is locally available for local construction rather than bringing higher quality rock from elsewhere at greater expense.
