In geochemistry, geophysics and nuclear physics, primordial nuclides, or primordial isotopes, are nuclides found on Earth that have existed in their current form since before Earth was formed. Primordial nuclides were present in the interstellar medium from which the Solar System was formed, and were formed in the Big Bang, by nucleosynthesis in stars and supernovae followed by mass ejection, by cosmic ray spallation, or from other processes throughout the history of the universe. They are the stable nuclides plus the fraction of the long-lived radionuclides surviving from the primordial solar nebula through planet accretion until the present; 286 such nuclides are known.
