text: Metals in Earths inner core could possibly be in the chain-melted state, as suggested by several simulations, where metals such as titanium and iron displayed partially molten states, or quasi-solid properties. It is also possible that Earths mantle may contain metals like potassium in the chain-melted state; however, potassium is usually not found in pure form.
  These suggestions may also possibly be proven by the Kola superdeep borehole, where according to declassified documents, the rock at the bottom of the borehole was found to be in a texture between solid and liquid.
