The mineral halite has bonds which form a cubic crystal lattice

Halite also known as rock salt, is a naturally occurring salt and mineral in the earth. The chemical formula of halite is repeating unit of NaCl. The bond that exist between an NaCl is ionic bonding. By definition, Ionic bonding is the union of a metal and a nonmetal. Thus the mineral Halite has Ionic bonds which form a cubic crystal lattice.

That result from subduction of oceanic plates beneath lighter continental plates. most of the earth's volcanoes are located around the pacific ring of fire because that the location of most of the earth's subduction zones.
