The highest quarries were at Rammius at 1,438 metres (4,718 ft). Quarried stone had to be dropped down slipways to the wadi below. [6] The central complex had a workers' settlement, a fort, temples to Sarapis and Isis Megiste, a bath with a hypocaust and a cemetery. [1] [7] The temple of
The Fort Riley Limestone is a Kansas Permian stratigraphic unit of member rank and historic building stone, sold commercially as fine-grained Silverdale, having at one time been quarried at Silverdale, Kansas. [4]
According to Marble.com, in 2016 there were 276 quarries producing natural stone in 34 states, and states producing the most granite were Texas, Massachusetts, Indiana, Wisconsin, and Georgia. [1] The term "quarry" refers also to sites producing aggregate, molding sand, or other resources besides cut stone.
The quarry is now a Site of Nature Conservation Importance (SNCI). Public access is free. [26] The quarry is also a prime location for geological research and provides opportunities for field studies in a variety of disciplines: sedimentology, stratigraphy, palaeontology, geography, and industrial archaeology. Several features make this a ...
Stone was extracted by the "room and pillar" method, by which chambers were mined, leaving pillars of stone to support the roof. [1] These mines were once owned by Postmaster General Ralph Allen (1694–1764). The mines contain a range of features including well preserved tramways, cart-roads and crane bases.

It seems likely that the rock quarried in the northern part of the district is the lateral equivalent in part at any rate to the conglomerates of Alderley Edge which die out ...
