The origin of magnesium is rooted in astrophysics processes taking place in the universe since the Big Bang (Schlesinger, 1997). It is assumed that in the second phase of star development, the combustion of helium yielded 126C, which subsequently underwent fusion, leading to the formulation as follows:

where γ is a photon. As a result of different fusion processes, magnesium occurs in three stable isotopes,

namely, 24Mg (78.99% of relative contribution), 25Mg (10%), and 26Mg (11.01%) (Rosman and Taylor, 1998).
