Editing Kamacite (section)

===Important minor elements, substitutions, solid solutions===
Kamacite sulfurization has been done experimentally in laboratory conditions. Sulfurization resulted in three distinct phases: a mono-sulfide [[solid solution]] ({{chem|Fe|x|(Ni,Co)|1-x|S}}), a pentlandite phase ({{chem|Fe|x|(Ni,Co)|9-x|S|8}}), as well as a P-rich phase. This was done in a lab to construct conditions concurrent with that of the solar nebula. With this information it would be possible to extract information about the thermodynamic, kinetic, and physical conditions of the early solar system. This still remains speculatory as many of the sulfides in meteorites are unstable and have been destroyed.<ref>{{cite journal |last1=Lauretta |first1=D. |title=Kamacite sulfurization in the solar nebula |journal=Meteoritics & Planetary Science |year=1998 |volume=33 |issue=4 |page=4 |doi=10.1111/j.1945-5100.1998.tb01689.x|bibcode=1998M&PS...33..821L |doi-access= }}</ref> Kamacite also alters to [[tochilinite]] ({{chem|Fe|2+| · 5-6 (Mg, Fe|2+|)|5|S|6|(OH)|10}}). This is useful for giving clues as to how much the meteorite as a whole has been altered. Kamacite to tochilinite alteration can be seen in petrologic microscopes, scanning electron microscope, and electron microprobe analysis. This can be used to allow researchers to easily index the amount of alteration that has taken place in the sample. This index can be later referenced when analyzing other areas of the meteorite where alteration is not as clear.<ref>{{cite journal |last1=Palmer |first1=E.
