Name:
Ellestadite (sensu lacto) was first described and named in honor of Dr. Ruben B. Ellestad (1900-1993), American analytical chemist of Minneapolis. Based on the chemical analysis, the type specimen of ellestadite should be considered a hydroxylellestadite (Pasero et al. 2010). Later Harada et al. (1971) described hydroxylellestadite. It was renamed as ellestadite-(OH), and again, by IMA 2010 (Pasero et al. 2010) back to hydroxylellestadite. The crystal structure was refined, first by Sudarsanan (1980), Hughes & Drexler (1991) and later by Onac et al. (2006).
A mineral in the Ellestadite Group of the Apatite Supergroup. Fluorellestadite-Hydroxylellestadite Series; Hydroxylapatite-hydroxylellestadite series. The hydroxyl analogue of fluorellestadite.
Formerly called ellestadite-(OH).
It is found in pegmatite veins, skarn and pyrometamorphic deposits.
Sulfate may be substituted by carbonate, at least in part, to give Unnamed (CO3 analogue of hydroxylellestadite) if the 50% rule is met.
