Additional information / Summary
Umbenannt von Uranpyrochlor in Uranopyrochlor. In allen studierten Fällen ist das U-Kation nicht die dominante Valenz an der A Position. Mit Ausnahme der Probe von Chakhmouradian and Mitchell (2002). Unabhängig davon ist es nicht möglich das dominate Anion auf der dominaten Valenz auf der Y-Seite des Minerals festzulegen. Daher sollten alle Uranpyrochlor in Uranopyrochlor umbenannt werden. Der Uranopyrochlor von Hogarth und Horne (1998) ist Natropyrochlor. |
