Hiortdahlite from Jingera, New South Wales

Niocalite and wöhlerite from the alkaline and carbonatite rocks at Kaiserstuhl, Germany

“…Compositional fields for each mineral based on 71 microprobe analyses from this study, and from 28 analyses from the literature. Literature sources are: for cuspidine from Skye, and Vesuvius (Tilley, 1947), from Franklin (Leavens et al, 1987); niocalite from Oka (Nickel et al, 1958;Mellini, 1982); wOhlerite from Angola, Brevik, Guyana, Oka, and Prairie Lake (Mariano and Roeder, 1989), from Junguni (Woolley and Platt, 1988); hiortdahlite from Jingera, Langesund, Tuva, and Vesuvius (Eggleton et al, 1979), from Kipawa (Aarden and Gittins, 1974), from Langesund (Br0gger and Cleve, 1889); l~venite from Burpala, Lovozero, S. Norway, and Central Tutarsk massif (in Portnov and Siderenko, 1977), from Tenerife (Ferguson, 1978 …”

Nomenclature of wöhlerite-group minerals

“…Therefore, we have explored the feasibility of 1) distinguishing wöhlerite group minerals from related minerals and 2) classifying WGMs down to species level solely based on EPMA data. We have used a total of 908 analyses of WGM and related minerals from our own work and the literature: Aarden and Gittins, 1974;Ferguson, 1978;Eggleton et al 1979;Raade and Mladeck, 1983;Hermezi et al 1986;Marino and Roeder, 1989;Merlino et al 1990;Keller and Williams, 1995;Sharygin et al 1996a,b;Chao and Gault, 1997;Jamtveit et al 1997;Stoppa et al 1997;Atencio et al 1999;Perchiazzi et al 2000;Roda-Robles et al 2001;Shiraga et al 2001;Federico and Peccerillo, 2002;Christiansen et al 2003;Bellezza et al 2004a,b;Mitchell and Belton, 2004;Casillas et al 2008;Chakhmouradian et al 2008;Andersen et al 2010;Friis et al 2010 Before attempting a classification or discrimination of species based purely on chemistry all data were recalculated based on 18 anions. We have maintained the identification of each analytical point as given in the respective papers, i.e.…”

“…Hiortdahlite, Na 2 Ca 4 (Ca 0.5 Zr 0.5 )Zr(Si 2 O 7 ) 2 OF 3 , one of the oldest WGM known, was described from the Langodden pegmatite occurring in the nepheline-syenite of Langesundsfjord, Norway (Brøgger, 1890a(Brøgger, , 1890b. Hiortdahlite is observed in several localities across the world and has been studied from the Korgeredaba alkaline Massif, Tuva, Russia (Kapustin and Bykova, 1965); Jingera, Australia (Eggleton et al, 1979) and Los Archipelago, Guinea (Biagioni et al, 2012).…”
