geocroniten.

/dʒiˈɑkrəˌnaɪt/

Forms: 1800s– geocronite, 1800s– geokronite.

Origin: From a proper name, combined with English elements; modelled on a Swedish lexical item. Etymons: geo- comb. form, proper name Κρόνος , -ite suffix¹.

Etymology: < geo- comb. form (with reference to antimony, one of the constituent elements, being represented in alchemy by the astrological symbol of the earth) + ancient Greek Κρόνος, the name of the god identified with Saturn (in alchemy associated with lead; see Cronian adj.) + -ite suffix¹, after Swedish geokronit (L. F. Svanberg 1839, in Konglig Vetenskapsacademiens handlingar för år 1839 (1841) 184). Compare German Geokronit (1840 in an abstract of the Swedish paper), French géocronite (1841 in an abstract of the Swedish paper).

Mineralogy.

A grey to grey-blue mineral consisting of a sulphide of lead, antimony, and arsenic and typically occurring as massive or granular deposits in hydrothermal veins.Chemical formula: Pb₁₄Sb₅AsS₂₃. Crystal system: orthorhombic.
