Mar 25, 2019· Ice is a mineral, even though it isn't listed in the mineral field guide. When ice collects in large enough bodies, it flows in its solid state -- that's what glaciers are. And salt behaves similarly, rising underground in broad domes and sometimes spilling out in salt glaciers. Indeed, all minerals, and the rocks they are part of, slowly deform given enough heat and pressure.
