WebbEndogenous Magmatic processes. Fractional crystallization: separates ore and non-ore minerals according to their crystallization temperature.As early crystallizing minerals form from magma, they incorporate certain elements, some of which are metals.These crystals may settle onto the bottom of the intrusion, concentrating ore minerals there. WebbThe composition of magma depends on the rock it was formed from (by melting), and the conditions of that melting. Magmas derived from the mantle have higher levels of iron, magnesium, and calcium, but they are still likely to be dominated by oxygen and silicon. WebbA volcano is a fissure – opening or vent – in the earth’s crust through which molten rocks and gases erupt. The molten rocks can be in the form of mixture of hot gases, ash, lava, or other extremely hot substances within the earth’s crust.
