    Q20.1 Where does it come from?

    Responses will vary

    Q20.2 The importance of heat and heat engines

    Deposit Type Is Heat a Factor? If So, What Is the Role of the Heat?
    Magmatic Yes Heat is necessary for melting of the rock to produce magma
    Volcanogenic massive sulphide Yes Heat is necessary for melting of the rock to produce magma
    Porphyry Yes Heat contained within the porphyritic intrusion drives the convection system
    Banded iron formation No Iron is deposited from cold ocean water
    Unconformity-type uranium Probably Uranium solubility is enhanced at higher water temperatures

    Q20.3 Sources of important lighter metals

    Element Silicon Calcium Sodium Potassium Magnesium
    Source(s) quartz sand lime-stone halite (NaCl) sylvite (KCl) dolomite ((Ca,Mg)CO3), magnesite (MgCO3), salt lakes and the ocean
