Quarry
place from which dimension stone, rock, construction aggregate etc. has been excavated from the ground
A quarry is a place where rock and earth materials – such as limestone, marble, granite, gravel, and sand – are excavated. The operation of quarries is regulated in some jurisdictions to manage their safety risks and reduce their environmental impact.
History
The stone industry is one of the oldest in the world. Creation of stone tools (microliths industry) in the region of South Africa has been dated to about 70,000–60,000 years ago. Granite and marble mining has existed as far back as ancient Egypt. Crushed stone was used extensively by the first great road building civilizations, such as ancient Greece and ancient Rome.
In the 18th century, the use of drilling and blasting operations was mastered.

This brief starts where responsible research should: with the source description of “Quarry” as place from which dimension stone, rock, construction aggregate etc. has been excavated from the ground. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as place from which dimension stone, rock, construction aggregate etc. has been excavated from the ground. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 29, 2026. The linked authority identifier is Q188040. The Library of Congress control number is sh85109481. None of the 1 selected statements returned an explicit reference.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
