Dolomite is a rock that contains both magnesium carbonate and calcium carbonate. As rocks it can have a widely varying percentage of magnesium carbonate. When it is ground up and sold for agricultural use it is sometimes called dolomitic lime - which means it contains a significant proportion of magnesium and not just a trace of it. Lime is not a specific material, but a mix of calcium compounds, but we also use that term for calcium oxide, which is corrosive. Dolomitic lime is just about any calcium and magnesium containing rock that you want to call it. (All of this is just my opinion, based on a lot of reading over several years. You know, rocks are very rarely anything close to a pure chemical compound, and dolomite is commonly what one group of rocks is called.)
