Ground Collapse: Old mines and prospects and sinkholes - NC

A sinkhole starts when water seeps down into limestone or other soluble rock like dolomite or marble, following cracks in the rock (fig. 18). Limestone lies under much of the southeastern Coastal Plain counties (fig. 17). The water dissolves the limestone, creating cavities. As the limestone is dissolved, a water-filled cavity forms.

Limestone vs Dolomite: What Are They, And What's The Difference?

Dolomite is a type of limestone that contains magnesium crystals. The Dolomite is slightly more complex than limestone. Limestone has a hardness of 3, while Dolomite has a hardness of 3.5 to 4. Dolomite smolders more slowly than calcite. Dolomite effervesces gradually with dilute hydrochloric acid, whereas calcite fizzes vigorously.

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details. Stone surface material may be lost all over or only in spots that are more reactive.

Limestone - Wikipedia

Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium.Calcite in limestone is divided into low-magnesium and high-magnesium ...

Difference Between Limestone and Marble

The name 'marble' is derived from a Greek word meaning "shining stone". Pure white marbles are obtained from very pure forms of limestone or dolomite rock, and the colored marbles are a result of impurities present in the parent rock. Generally high amounts of magnesium in limestone give a greenish tint to the marble.
