zirkeliten.

Brit.

/ˈzəːkəlʌɪt/, U.S.

/ˈzərkəˌlaɪt/

Origin: From a proper name, combined with an English element. Etymons: proper name Zirkel , -ite suffix¹.

Etymology: < the name of Ferdinand Zirkel (1838–1912), German mineralogist + -ite suffix¹.

Mineralogy.

A black or dark brown mineral which is a mixed oxide of zirconium, calcium, titanium, thorium, and other elements, occurring as small prisms or, more commonly, in amorphous form.Chemical formula: (Ca,Th,Ce)Zr(Ti,Nb)₂O₇. Crystal system: cubic.

Very similar to zirconolite n. and not always distinguished from it: see note at that entry.
