The term karst describes a distinctive topography that indicates dissolution (also called chemical solution) of underlying soluble rocks by surface water or ground water. Although commonly associated with carbonate rocks (limestone and dolomite) other highly soluble rocks such as evaporates (gypsum and rock salt) can be sculpted into karst terrain. Fossils are common in limestone. Limestone fizzes in dilute hydrochloric (HCl) acid, because it is composed of the mineral calcite, CaC03. Some limestone contains chert, which is very, very hard silica (like flint). It typically weathers to brown on the surface and occurs in nodules and occasionally replaces fossil shells.Indiana limestone is a more common term for Salem Limestone, a geological formation primarily quarried in south central Indiana, USA, between the cities of Bloomington and Bedford.
