Degrading concrete has been the focus of many studies and the most obvious sign is calcium-rich leachate seeping from a concrete structure. [5] [6] [7]Calthemite stalactites can form on concrete structures and "artificial caves" lined with concrete (e.g. mines and tunnels) significantly faster than those in limestone, marble or dolomite caves.
The matrix is typically composed of argillaceous carbonate, such as clay ironstone, while the crack filling is usually calcite. [36] [34] The calcite often contains significant iron (ferroan calcite) and may have inclusions of pyrite and clay minerals. The brown calcite common in septaria may also be colored by organic compounds produced by ...

The Michigan Limestone and Chemical Company operated the world's largest limestone quarry (Michigan Limestone; a/k/a the "Calcite Quarry"; "Calcite Plant and Mill"; and "Carmeuse Lime and Stone"), which is located near Rogers City in Presque Isle County, Michigan. It was formed and organized in 1910; however, production did not begin until 1912.

As this happens with increasing time, fluid cools, evolves by mixing with other fluids and when it forms magnesite, it decreases its temperature.
