Dolomite, also known as dolostone and dolomite rock, is a sedimentary rock composed primarily of the mineral dolomite, CaMg(CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater.olomite has a Mohs hardness of 3.5 to 4 and limestone (composed of the mineral calcite) has a hardness of 3. Dolomite is slightly less soluble in dilute hydrochloric acid. Calcite will effervesce vigorously in contact with cold, dilute (5%) hydrochloric acid, while dolomite produces a very weak effervescence.
Costs Vary Widely. Nationally, estimates of room addition costs vary from $80 to $250 a square foot. A simple room addition with a basic foundation and no plumbing generally costs at least $100 a square foot with typical internal finishing, no expansion of a heating/cooling unit, and minimal structural changes.

The costs associated with adding a new room onto your home can be broken down into labor and materials.
