Limestone: Limestone is one of ...Calcite in limestone is divided into low-magnesium and high-magnesium calcite, with the dividing line placed at a composition of 4% magnesium. High-magnesium calcite retains the calcite mineral structure, which is distinct from dolomite. Aragonite does not usually contain significant magnesium. [8]In continuous operation since 1912, the Calcite Quarry has shipped well over 700 million tons of high quality limestone to customers throughout the midwest. The limestone was deposited over 350 million years ago when the area was submerged in a shallow sea. The calcium in the water settled out and formed a deposit that is hundreds of feet thick.After precipitation of gypsum, the brine is both enriched in Mg relative to Ca and has a higher density. If the brine then enters the groundwater system and moves downward into buried limestones. This Mg-rich brine then reacts with the calcite in the limestone to produce dolomite. Mixing of Seawater and Meteoric Water.Limestone is a carbonate sedimentary rock that consists predominantly of calcite [CaCO 3].
