A surface vein was identified on the Martian surface.<br /> <br /> The main use of Calcium sulfate, when adequately treated with heat (dehydrated), is plaster of Paris, or stucco. This is used as a finishing compound, or as an element of drywall construction. Drywall construction can provide fire safety for structural elements.</div>
