The Allende meteorite contained an abundance of 26Mg, an isotope of magnesium. 26Mg is the stable product of the decay of radioactive 26Al. What is the significance?
A) Magnesium has a high melting point, so the asteroid of which Allende was originally a part must have formed in the inner part of the solar system.
B) ( The decay of 26Al would have produced enough radioactivity to cause the melting and differentiation of the Allende meteoroid.)
C) The 26Al from which the 26Mg formed was probably produced in a nearby supernova explosion about the time the solar system was formed.
D) This discovery suggests that heavy elements such as magnesium were more abundant in the early Kuiper belt than originally thought.
