Pigeonit ist ein selten vorkommendes Mineral aus der Mineralklasse der „Silikate und Germanate“ mit der chemischen Zusammensetzung (Mg,Fe,Ca)2[Si2O6]. Die in den runden Klammern angegebenen Elemente Magnesium, Eisen und Calcium können sich dabei in der Formel jeweils gegenseitig vertreten (Substitution, Diadochie), stehen jedoch immer im selben Mengenverhältnis zu den anderen Bestandteilen des Minerals. Pigeonit kristallisiert im monoklinen Kristallsystem und entwickelt prismatische, bis zu einem Zentimeter große, durchscheinende Kristalle mit einem glasähnlichen Glanz auf den Oberflächen. Meist findet er sich allerdings in Form glanzloser (matter), körniger bis derber Mineral-Aggregate. Das Mineral ist im Allgemeinen von brauner, grünlichbrauner oder schwarzer Farbe, kann in dünnen Schichten aber auch farblos oder hellgelblichgrün bis bräunlichgrün erscheinen. Seine Strichfarbe ist dagegen immer grauweiß. Піжоні́т (рос. пижонит; англ. pigeonite; нім. Pigeonit m) — мінерал, складний силікат кальцію, магнію та двовалентного заліза, групи піроксенів. La pigeonite est un minéral d'aspect vitreux et mat, et de couleur brune — qui peut être un brun pourpré, violet ou verdâtre — ou noire. De formule chimique (Mg,Fe,Ca)2(SiO3)2, c'est un clinopyroxène, c’est-à-dire un silicate de la famille des inosilicates à chaîne simple ; c'est une solution solide peu calcique, variant surtout d'un pôle ferrifère à un pôle magnésien. Cristallisant dans le système cristallin monoclinique comme l'augite, elle en est cependant séparée par un hiatus de miscibilité. La pigeonite est présente dans des roches lunaires et des météorites. La pigeonite tire son nom de Pigeon Point dans le comté de Cook (Minnesota), péninsule inhabitée des rives du Lac Supérieur où elle a été découverte en 1900 par (it). La pigeonita és un mineral silicat del subgrup dels clinopiroxens. La seva fórmula és (Ca,Mg,Fe)(Mg,Fe)Si₂O₆, podent variar el contingut en calci del 5 al 25%.

It has a general formula of (Ca,Mg,Fe)(Mg,Fe)Si2O6. The calcium cation fraction can vary from 5% to 25%, with iron and magnesium making up the rest of the cations. Pigeonite crystallizes in the monoclinic system, as does augite, and a miscibility gap exists between the two minerals. At lower temperatures, pigeonite is unstable relative to augite plus orthopyroxene. The low-temperature limit of pigeonite stability depends upon the Fe/Mg ratio in the mineral and is hotter for more Mg-rich compositions; for a Fe/Mg ratio of about 1, the temperature is about 900 °C. The presence of pigeonite in an igneous rock thus provides evidence for the crystallization temperature of the magma, and hence indirectly for the water content of that magma. Pigeonite is found as phenocrysts in volcanic rocks on Earth and as crystals in meteorites from Mars and the Moon. In slowly cooled intrusive igneous rocks, pigeonite is rarely preserved. Slow cooling gives the calcium the necessary time to separate itself from the structure to form exsolution lamellae of calcic clinopyroxene, leaving no pigeonite present. Textural evidence of its breakdown to orthopyroxene plus augite may be present, as shown in the accompanying microscopic image. Pigeonite is named for its type locality on Lake Superior's shores at Pigeon Point, Minnesota, United States. It was first described in 1900. Het mineraal pigeoniet is een magnesium-ijzer-calcium-inosilicaat met de chemische formule (Mg,Fe2+,Ca)(Mg,Fe2+)Si2O6. Het behoort tot de clinopyroxenen.
