Hint: As we know that rock salt is a natural mineral composed of sodium chloride in major amounts along with impurities. It generally occurs at evaporite deposits of various minerals such as minerals of the sulfates, halides, carbonates and borates. So here we have to talk about rock salt along with its colour and the reason behind it.Web

Silica (SiO 2 ), in the form of chert, is the only silicate mineral that commonly forms a chemical sedimentary rock. Gypsum (CaSO 4 •2H 2 O), anhydrite (CaSO 4 ), halite (NaCl), and sylvite (KCl) consist of common elements. Ggypsum and anhydite have high solubilities; halite and sylvite have even higher solubilities.Web

Boron does not occur in nature in an elemental state. It is always found in oxidized states as borate salts. Four mineral forms account for the majority of the economically viable borate deposits throughout the world: two sodium borates, tincal and kernite; a calcium borate, colemanite; and a sodium-calcium borate, ulexite.
