...Wendy R. Nelson; Dana T. Griffen Abstract Rhodonite (ideally MnSiO 3 ) is a triclinic pyroxenoid that typically contains significant concentrations of Ca, Fe, and Mg. A variety called fowlerite contains concentrations of Zn up to 10 wt% and has been found only at Franklin, New Jersey. Data from...

...N. Sundius Abstract The following minerals are generally regarded as triclinic pyroxenes: rhodonite, bustamite, fowlerite, iron rhodonite, sobralite, and pyroxmangite. All these mineral species represent metasilicates of manganese with smaller or greater admixtures of CaSiO 3 , MnSiO 3 and FeSiO 3...

...A.N. Winchell Abstract The standard treatises on mineralogy all refer rhodonite, bustamite, fowlerite and babingtonite to the triclinic pyroxenes, but show no agreement at all regarding the other members of the group. Dana 1 includes hiortdahlite in the group, but it is excluded by others because...

... for this variety is the famous Franklin zinc deposit, Sussex Co., New Jersey, USA. It was initially named ‘fowlerite’ (Shepard, 1832 ) but was later identified as a Zn-rich variety of rhodonite (Camac, 1852 ). Available structural data indicate that the M (4) site tends to concentrate cations smaller than...

... circles: blue – rhodonite; light purple – vittinkiite; deep purple – synthetic analogue of the end-member vittinkiite; red – ferrorhodonite; green – Zn-rich variety of rhodonite (‘fowlerite’); and grey – Mg-enriched variety of rhodonite. Other vittinkiite samples are shown by empty purple circles whereas...

.... A range of synthetic and natural standards was used for calibration. Standards for sulfide analysis were galena (S); Nb, Ta, Ni, and Cu metals, rutile (Ti); and hematite (Fe, O). Standards for silicate glass analysis were wollastonite (Ca, Si), periclase (Mg), rutile (Ti), albite (Na, Al), fowlerite (Mn...
