monzoniten.

Brit.

/mɒn(t)ˈzəʊnʌɪt/, U.S.

/mɑn(t)ˈzoʊˌnaɪt/

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

Etymology: < the name of Mount Monzoni, a mountain in the Tyrol, north-eastern Italy, + -ite suffix¹. In sense 1 (in mineralogy) after German Monzonit (F. von Kobell 1871, in Sitzungsberichte der Math.-Physikalischen Classe der Königl. Bayerischen Akad. der Wissensch. zu München 1 162). In sense 2 (in petrography) after French monzonite (A. de Lapparent 1864, in Ann. des Mines 6 259).Mount Monzoni is the type locality of both the mineral and the rock.

1. Mineralogy. An aluminosilicate of ferrous iron and calcium resembling green hornstone. Now historical.

1882 G. J. Brush Appendixes to Fifth Ed. of Dana's Mineral. i. 11 Monzonite..resembles green hornstone... Found on the Monzoni Mt. in the valley of Fassa, Tyrol.

1993 A. M. Clark Hey's Mineral Index (ed. 3) 469/2 Monzonite (of Kobell), aluminosilicate of alkalis, Fe²⁺, and Ca.

2. Geology. A granular igneous rock with a composition intermediate between syenite and diorite, spec. one containing approximately equal amounts of orthoclase and plagioclase.

1974 Encycl. Brit. Macropædia IX. 222/2 In general appearance and in field relations monzonites resemble granitic rocks; they differ from granites by reason of their lower quartz content.

1990 Jrnl. Petrol. 31 524 The porphyritic quartz monzonite contains euhedral hornblende crystals that are always more abundant than biotite.
