Valid as an unnamed mineral
This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Ce,La,Ca)9(Fe,Mg)(SiO4)3[SiO3(OH)]4(F,Cl,OH)3 · nH2O (?)
Very close to a bit hydrated, F-analogue of cerite-(CeCa). Reported as "unnamed mineral "E sample A37"". Possibly of cerite subgroup?

Co-described with UM2007-35-SiO:AlCaFFeMgREE, fluorbritholite-(Y), magnesiorowlandite-(Y) (?), UM2007-36-SiO:AlCaFFeMgREE, UM2007-39-SiO:ClFHMgREE, delhuyarite-(Ce), and UM2007-44-SiO:CaFREEY.
