Compositions of olivine are commonly expressed as molar percentages of forsterite ( Fo ) and fayalite ( Fa ) ( e . g ., Fo 70 Fa 30 ).
22.
The bottom of the furnace also fills with molten slag, often consisting of fayalite, a compound of silicon, oxygen and iron mixed with other impurities from the ore.
23.
Fayalite forms solid solution series with the magnesium olivine endmember forsterite ( Mg 2 SiO 4 ) and also with the manganese rich olivine endmember tephroite ( Mn 2 SiO 4 ).
24.
Other examples of series include the olivine series of magnesium-rich forsterite and iron-rich fayalite, and the wolframite series of manganese-rich h�bnerite and iron-rich ferberite.
25.
The small particles of iron produced in this way fall to the bottom of the furnace, where they combine with molten slag, often consisting of fayalite, a compound of silicon, oxygen and iron mixed with other impurities from the ore.
26.
For example, the olivine group is described by the variable formula ( Mg, Fe ) 2 SiO 4, which is a solid solution of two end-member species, magnesium-rich forsterite and iron-rich fayalite, which are described by a fixed chemical formula.
27.
Iron may only enter minerals such as pyroxene and olivine if it is present as Fe 2 +; Fe 3 + cannot enter the lattice of fayalite olivine and thus for every two Fe 3 + ions, one Fe 2 + is used and one molecule of magnetite is created.
28.
The two unoxidised ferrous ( Fe 2 + ) ions still available in the three formula units of fayalite finally combine with the four ferric ( Fe 3 + ) cations and oxide anions ( O 2 " ) to form two formula units of magnetite ( Fe 3 O 4 ).
29.
In the absence of atmospheric oxygen ( ), in deep geological conditions prevailing far away from Earth atmosphere, hydrogen ( ) is produced during the process of serpentinization by the anaerobic oxidation by the water protons ( H + ) of the ferrous ( Fe 2 + ) silicate present in the crystal lattice of the fayalite (, the olivine iron-endmember ).
