Natro-glauconite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
(Na,K)(Fe3+,Al,Mg)2((Si,Al)4O10)(OH)2
Name:
Name proposed in 1998 by the IMA for the sodium-dominant equivalent of glauconite (Rieder et al, 1998). The previous similar name "soda-glauconite" was not named for a sodium-dominant member of the series and should not be used, except as a variety of glauconite, sensu strictu.
This page provides mineralogical data about Natro-glauconite.
