About SuessiteHide

Hans E. Suess
Specific Gravity:
7.08 (Calculated)
Crystal System:
Named in honor of Hans Eduard Suess (29 December 1909, Vienna, Austria - 20 September 1993, La Jolla, California, USA), physical chemist, nuclear physicist, and professor of chemistry, University of California at San Diego, USA in recognition of his outstanding contributions to the field of cosmochemistry and meteoritics. He received the V. M. Goldschmidt Award in 1974.
Compare xifengite and mavlyanovite.

Uncommon accessory in some iron meteorites.

One of many natural Fe-Si phases; beside the approved species (xifengite and other ones listed below) you may want to compare Unnamed (Fe silicide I), Unnamed (Fe silicide II) and UM2000-60-Si:Fe.

Compare carletonmooreite.
