Halite: rock salt
Back
Halite: rock salt. Lower Carboniferous. Near Sussex, New Brunswick. Collector: unknown. New Brunswick Museum (NBME 1159). Specimen width 7 cm. Halite, sometimes known as rock salt, was deposited during the Carboniferous, when the Windsor Sea flooded low-lying areas of the Maritimes Basin in western New Brunswick. As sea levels changed in the Carboniferous period, the salt water evaporated, concentrating the minerals into potash, salt and gypsum.
