    1. In igneous and metamorphic rocks, molten/liquid and gaseous minerals are forced upwards into the cracks. They then solidify and form veins or lodes.

    2. Igneous rocks form minerals from molten magma cooling; metamorphic rocks form minerals due to heat and pressure altering existing rocks, changing their composition without melting entirely.
