Much of the past work on measuring the isotopic composition of Fe has centered on determining 60Fe variations due to processes accompanying nucleosynthesis (i.e., meteorite studies) and ore formation.
Banyak riset masa lalu tentang pengukuran komposisi isotop Fe telah difokuskan pada penentuan variasi 60Fe karena proses yang menyertai nukleosintesis (yaitu, studi meteorit) dan formasi bijih.
