Dimension Stone Mining - Encyclopedia of Arkansas

The mining of dimension stone is labor intensive, and the cost of the product delivered to an end user is tied to both labor and transportation costs. Rough Stone Rough stone may be subdivided into field stone and rounded river stone. Field stone typically is simply picked up from loose debris material present on hillsides. It may or may not be covered with moss and typically has minor rounding due to

Dimension stone - Wikipedia

Dimension stone is natural stone or rock that has been selected and finished (e.g., trimmed, cut, drilled, ground, or other) to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to endure and to maintain its essential and distinctive characteristics of strength, resistance to decay, and appearance.
