To the west and north these rocks are known as the Amherstburg Formation of the Detroit River Group. [2] Northwest of Ingersol and Woodstock, across the crest of the Algonquin Arch, the band of outcrop turns more northerly, and strikes north-northwest for about 140 km to the east shore of Lake Huron in the Kincardine area (as shown in the map ...
The Chazy Reef Formation is a mid-Ordovician limestone deposit in northeastern North America. It consists of some of the oldest reef systems built by a community of organisms [ 1 ] rather than the deposit of a limited range of similar organisms, such as Stromatolite mounds deposited by ancient cyanobacteria.
The Pottsville Formation consists of a gray conglomerate, fine to coarse grained sandstone, and is known to contain limestone, siltstone and shale, as well as anthracite and bituminous coal. [4] [5] It is considered a classic orogenic molasse. [6] The formation was first described from a railroad cut south of Pottsville, Pennsylvania. [4]
The Platteville Limestone cropping out in Minnehaha Park, Minneapolis. The Platteville Limestone is the less-eroded, layered unit that constitutes the majority of the photo. Below it is a thin, dark layer of Glenwood Shale. Below the shale is a thin, white stripe of St. Peter Sandstone, followed by a slope of eroded St. Peter Sandstone material.
Indiana limestone (also known as Bedford limestone) is a form of limestone used as a building material, particularly for monumental public structures. Some 35 of the 50 state capitol buildings in the United States are made of Indiana limestone, [ 1 ] as are the Empire State Building , Biltmore Estate , the Pentagon and National Cathedral in ...
The Manlius Limestone was first noted by Vanuxem (1840, p. 372) as a "waterlime" (hydraulic limestone) near Manlius, New York. [5] The Manlius is composed of limestone , grainstone , calcareous mudstone and bindstone .
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 ...
