Potassic-jeanlouisite from Leucite Hill, Wyoming, USA, ideally K(NaCa)(Mg 4 Ti)Si 8 O 22 O 2 : the first species of oxo amphibole in the sodium–calcium subgroup
Journal: Mineralogical Magazine
Published: 01 August 2019
Mineralogical Magazine (2019) 83 (4): 587–593.
...Roberta Oberti; Massimo Boiocchi; Frank C. Hawthorne; Giancarlo Della Ventura; Gunnar Färber Abstract Potassic-jeanlouisite, ideally K(NaCa)(Mg 4 Ti)Si 8 O 22 O 2 , is the first characterised species of oxo amphibole related to the sodium–calcium group, and derives from potassic richterite via...
