Sidorovite (original) (raw)

A valid IMA mineral species

Specific Gravity:

11.815 (Calculated)

Name:

Named in honor of Evgeniy Gennadievich Sidorov (1955–2021), Russian geologist and mineralogist at the Institute of Volcanology and Seismology of the Far East Branch of the Russian Academy of Sciences. He played a significant role in the discovery of the Koryak-Kamchatka Platinum Belt and is a co-author of 71 new minerals discovered in Kamchatka.

Suggested to form via incorporation of Fe0 by tetraferroplatinum, through the reduction of Fe via H2-bearing fluids derived from serpentinization of olivine at T <450 °C.

Powder Diffraction Data:

Comments:

Three calculated lines at 1.527, 1.128, and 1.080 Å with intensities >10 were not discernible, likely due to the strong overlap with peaks from associated minerals (ex. tetraferroplatinum).
