If limestone and dolomite exist in different layers, acid at low to moderate temperatures (below 50 °C) diverts itself towards the limestone, leaving the dolomite unstimulated. At high temperatures, where dolomite's reaction becomes mass transfer limited, the acid invades both layers of limestone and dolomite equally. ...

Limestone. More than 50 percent of the surface rocks in Kentucky are limestones. Limestone is chiefly composed of the mineral calcite (calcium carbonate), but may contain small amounts of clay, silt, chert, and dolomite. Most limestones are layered and contain fossils of shellfish and other animals that lived in shallow seas.

What Are The Physical Characteristics of Dolomite? Dolomite typically has a Mohs hardness of 3.5 to 4, making it somewhat soft and easy to work with. It's also relatively lightweight, with a specific gravity of 2.8 to 2.9. Additionally, dolomite is chemically inert, meaning it won't react with other materials.
