...Sergey N. Britvin; Sergey V. Krivovichev; Thomas Armbruster Abstract Ferromerrillite, ideally Ca 9 NaFe 2+ (PO 4 ) 7 , is a new mineral related to the whitlockite group. It occurs as a common accessory phase in several Martian meteorites classified as basaltic and olivine-phyric shergottites...

... into two subgroups: merrillite (merrillite, ferromerrillite, keplerite and matyhite) and whitlockite (whitlockite, strontiowhitlockite, wopmayite and hedegaardite). Cerite-(La) has been renamed ferricerite-(La). The new nomenclature has been approved by the International Mineralogical Association...

... of merrillite component has been found in terrestrial whitlockite ( Hughes et al. 2008 ). An Fe-dominant analog of merrillite, identified as a separate mineral species in several martian meteorites (shergottites), was named ferromerrillite ( Britvin et al. 2016 ). Below, we present characteristics of the first...

Abundant, though volumetrically minor, sulfide-merrillite assemblages are found in CV3 carbonaceous chondrites ( Rubin and Grossman 1985 ), who propose that phosphate minerals formed...
