UM2007-46-SiO:CaHREEThTi

Valid as an unnamed mineral
This page is currently not sponsored. Click here to sponsor this page.
Formula:
~(Ti,Th,REE,Ca)Si2O4(O,OH)2 · 4-6H2O
rather variable composition
Co-described with another Th-rich species: UM2007-45-PO:AlHCaKNaSiTh, UM2007-47-SiO:HKNaTh, UM2007-48-SiO:HNaSrThTi, and UM2007-49-SiO:HNaSrThTi.

Metamict.

Corresponds to "Table 4, anal. 4, 7, 8 & 9".

Could, possibly, represent one of the (chemically) simplest Ti silicates in the nature.
