Edscottite (IMA 2018-086a), Fe₅C₂, is a new iron carbide mineral that occurs with low-Ni iron (kamacite), taenite, nickelphosphide (Ni-dominant schreibersite), and minor cohenite in the Wedder-burn iron meteorite, a Ni-rich member of the group IAB complex. 

The new mineral and its name have been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (IMA 2018-086a) (Ma and Rubin 2019). The mineral name is in honor of Edward (Ed) R.D. Scott (born in 1947), esteemed cosmochemist at the University of Hawai‘i at Manoa, U.S.A., for his multifaceted contributions to research on meteorites. He discovered haxonite, (Fe,Ni)₂₃C₆ (Scott 1971), as well as this new iron carbide in Wedderburn. The new carbide phase was described as forming plates a few micrometers thick within kamacite (Scott and Agrell 1971; Scott 1972). The type specimen of edscottite is in Wedderburn polished thick section UCLA 143, housed in the Meteorite Collection of the Department of Earth, Planetary, and Space Sciences, University of California, Los Angeles, California, U.S.A.
