UM1972-13-SCO:CaFeH

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(FeS)2(CaCO3 · H2O)0.84
Crystal System:
Hexagonal
Reported as one of two fibrous phases ("Type I"); as fine-grained aggregates and/or veinlets of fibrous crystals around troilite from nearby Pefkos, Cyprus.

The "Type II" phase, 2FeS•(Mg0.53Fe0.47(OH)2) resembles tochilinite.

Bonded water confirmed by IR and DTA methods.

Optical and physical properties similar to those of valleriite. Compare 'ignicolorite'.
