quarryable

Quarryable is an adjective used to describe rock, mineral deposits, or formations that can be extracted from a quarry to produce stone or related products. In geology and the stone industry, a material is considered quarryable when it can be opened and quarried by surface methods delivering usable material at an economic margin.

Quarryability depends on physical and economic factors: rock type and consistency, thickness and continuity of the deposit, depth of overburden, fracture and faulting, and the presence of intact beds. Economic viability depends on market demand, extraction and processing costs, and transportation logistics.

Quarrying typically involves opening a series of benches at the surface, with drilling, blasting or mechanical cutting to remove blocks, followed by processing to produce aggregate or dimensional stone.

Common quarryable materials include limestone, granite, marble, sandstone, and slate, though not all deposits of these rocks are economically viable. Some rocks are profitable to quarry in large, well-situated quarries; others may be technically challenging or environmentally constrained.

The term contrasts with mineable, which can describe materials extracted by underground mining or from deposits not suitable for open-pit quarrying. Quarryability is therefore a function of geology, engineering feasibility, and regulatory and environmental considerations.
