Formation of limestone
The formation was renamed the Salem Limestone by Cumings in 1901 because the name Bedford was preoccupied by the Bedford Shale of Ohio (Newberry, 1871).A helictite is a speleothem found in limestone caves that changes its axis from the vertical at one or more stages during its growth. They have a curving or angular form that looks as if they were grown in zero gravity. They are most likely the result of capillary forces acting on tiny water droplets, a force often strong enough at this scale to defy gravity.

A limestone pavement is a natural karst landform consisting of a flat, incised surface of exposed limestone that resembles an artificial pavement. [1] The term is mainly used in the UK and Ireland, where many of these landforms have developed distinctive surface patterning resembling paving blocks. [2] Similar landforms in other parts of the ...The land that is now Ireland then moved north close to the equator, at this time, known as the Carboniferous period, a sea extended across Ireland allowing for the for the formation of sedimentary rocks such as sandstone and mudstone. Over the next 50 million years limestone deposits formed in the warm waters.At 87th and Blue Ridge Parkway, excavation exposed almost 1,000 feet of limestone and shale strata, described in Gentile’s “The Geology of Kansas City, Missouri,” an auto tour through the city.Importantly, limestone bedrock tells geologists that at the time of formation, that area was a shallow sea. Limestone formed in these environments because its main composition is calcium carbonate, which was deposited when shells and pieces of shells from small shallow water invertebrates settled down to the sea floor.
