It is used as a construction aggregate, in cement production, and as a dimension stone for building facades.
Yes, but they are often less distinct than in limestone because the chemical process of dolomitization can destroy or obscure original fossil shapes.
Using 'dolostone' for the rock and 'dolomite' for the mineral avoids ambiguity, especially in technical writing. This distinction is more rigid in North American usage.
