Limestone (calcium carbonate CaCO 3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO 3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place ...
The Tonto sandstone was officially renamed the Tapeats Sandstone and the Tonto shale was officially renamed the Bright Angel Shale. The Marbled limestone was later officially renamed the Muav Limestone, which by Noble's definition consisted of an upper set of dolomite beds and a lower set of limestone beds. [12]
The Muav Limestone is a Cambrian geologic formation within the 5-member Tonto Group. ... In 1914, L F. Noble [3] renamed Gilbert's three subdivisions of the Tonto Group.
The Marbled limestone was renamed as the Muav Limestone. L. F. Noble redefined his Muav Limestone as being the "...predominantly calcareous part of the Tonto group" lying beneath either the discontinuous lenses of overlying Devonian beds or base of the Redwall Limestone and overlying the Bright Angel Shale.

Caen Stone – Limestone quarried near Caen, France; Lutetian limestone – Type of limestone from Paris, or "Paris stone" (city buildings are widely faced with it) . Saint-Maximin – commune in Oise, France, or Oise, limestone (variety of Lutetian)
Except where underlain by the Sixtymile Formation, the Tapeats Sandstone is the Cambrian geologic formation that is the basal geologic unit of the Tonto Group.Typically, it is also the basal geologic formation of the Phanerozoic strata exposed in the Grand Canyon, Arizona, and parts of northern Arizona, central Arizona, southeast California, southern Nevada, and southeast Utah.
The Buda Limestone is a geological formation in the High Plains and Trans-Pecos regions of West Texas [1] and in southern New Mexico, [2] whose strata date back to the Late Cretaceous. Pterosaur remains are among the fossils that have been recovered from the formation.
The Kelly Limestone was the principal ore-bearing formation of the historic Magdalena, ... and the formation was renamed as the Kelly Limestone by C.H. Gordon in 1907 ...
