Brit.

/ˈpɪdʒᵻnʌɪt/, U.S.

/ˈpɪdʒəˌnaɪt/

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

Etymology: < the name of Pigeon Point in north-east Minnesota, where the mineral was first discovered + -ite suffix¹ (see quot. 1900 at main sense).

Mineralogy.

A mineral that is a silicate of magnesium, ferrous iron, and calcium, (Mg,Fe²⁺,Ca)₂Si₂O₆, being a monoclinic calcium-poor pyroxene substantially free of aluminium and ferric iron, and found chiefly in basic igneous rocks.

1900 A. N. Winchell in Amer. Geol. 26 204 Since the anomalous condition was first discovered in the rocks from Pigeon point, it would be appropriate to call pyroxene thus optically abnormal pigeonite.

1951 Jrnl. Geol. (Chicago) 59 480/1 Pigeonites under plutonic conditions invert with cooling to orthopyroxenes.

1993 Jrnl. Petrol. 34 743 The assemblage..is bounded by the appearance of pigeonite in the silica-rich compositions.

Derivatives

pigeoˈnitic adj. of the nature of or containing pigeonite.
