It crystallizes in the hexagonal crystal system (space group R3c). It is a member of the Cerite structural group.
IMA symbol Myh, IMA status: approved, named in 2016.
Found in an angrite meteorite as well-defined domains in association with Fe sulfide near the contact between fayalite-kirschsteinite overgrowth/symplectite and hedenbergite.
It is found associated with Kuratite, ulvöspinel, hedenbergite, Ca and Fe olivine, Fe sulfide.
The mineral was named to honor Professor Ting-Ying Hsüeh Ma (1899-1979), a palaeontologist who pioneered research into relations between coral growth rate, sea-water temperature, paleoclimate.
