Do rocks like limestone contain a chemical called sodium chloride?

Limestone is primarily composed of calcium carbonate (CaCO₃) and does not typically contain sodium chloride (NaCl), which is common table salt. Sodium chloride is more often found in evaporite deposits, such as rock salt, rather than in limestone. However, trace amounts of various minerals, including sodium, can sometimes be present in limestone due to environmental factors, but it is not a characteristic component.
