WebMetals mostly occur as compounds in rocks and minerals and must be extracted before they can be used. The method used to extract the pure metal depends on its position in the reactivity series. WebTectonic forces in the Earth cause huge masses of rock to be pushed and squeezed together, creating enormous amounts of stress and heat. These conditions allow for the original minerals of the protolith to gradually transform into minerals that are more stable at higher pressures and temperatures.
