Nomenclature/classification proposals approved in July 2020

IMA 20-C: Crystal structure and redefinition of utahite

Proposal 20-C is accepted, and the formula of utahite is redefined from Cu2+5Zn3(Te6+O4)4(OH)8∙7H2O
to MgCu2+4Zn2Te6+3O14(OH)4∙6H2O

Margarosanite group

The margarosanite groupis established and includes the three isostructural members: margarosanite, walstromite, and breyite.
Pascoite family

Pascoite family

The pascoite family is established and consists of 20 V minerals. The family consists of the pascoite and lasalite groups as well as a number of ungrouped members. In addition, the formula of rakovanite has been revised from Na3[H3V10O28]•15H2O to (NH4)3Na3[V10O28]•12H2O

Pascoit-Familiie
 
Gibt es schon irgendwo eine Gruppierung und Auflistung der Mineralien der Pascoit-Familie?

Viele Grüße
