Cobble encrusted with halite from the shore of Dead Sea

Cobble encrusted with halite evaporated from the western shore of the Dead Sea near Ein Gedi.

Halite, commonly known as rock salt, is the mineral form of sodium chloride (common salt or kitchen salt of chemical formula NaCl). Halite forms isometric crystals, typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on the amount and type of impurities contained in it. It commonly occurs with other evaporate deposit minerals such as many sulfates, halides, and borates.
