Rock salt is primarily composed of the mineral **halite**. Halite is the natural form of sodium chloride (NaCl) and is commonly found in evaporite deposits, where seawater or saltwater bodies have evaporated over time. Rock salt is mined for its use in various applications, including food seasoning, de-icing roads, and as a preservative.

To elaborate, halite typically forms from the evaporation of saline water, leading to the crystallization of sodium chloride. It is transparent to translucent and is often characterized by its cubic crystal structure and its salty taste. Other minerals listed, such as calcite (calcium carbonate), dolomite (calcium magnesium carbonate), and gypsum (calcium sulfate), are distinct and do not comprise rock salt. Therefore, the correct answer from the given options is halite.
