About Nöggerathite-(Ce)Hide

Jacob Nöggerath
Formula:
(Ce,Ca)2Zr2(Nb,Ti)(Ti,Nb)2Fe2+O14
Colour:
dark brownish-red to dark brownish-black
Lustre:
Adamantine
Hardness:
5 - 6
Crystal System:
Orthorhombic
Name:
The root name is given in memory of Johann Jacob Nöggerath (1788 - 1877), a prominent German mineralogist and geologist. Since 1818 J. J. Nöggerath was professor of mineralogy and geology at the University of Bonn. Among his publications, there is a geological description of the Laach Lake paleovolcanic region.
Isostructural with:
Nöggerathite-(Ce) is an analogue of zirconolite-3O, ideally CaZrTi2O7, with Nb dominant over Ti in one of two octahedral sites and REE dominant over Ca in the eight-fold coordinated site. Nöggerathite-(Ce) is also orthorhombic Ce-dominant analogue of laachite, (Ca,Mn)2Zr2Nb2TiFeO14
