Preface

Name from

Der Name Andychristyite ehrt Andrew (Andy) Gregor Christy (geboren 1963) ein walisisch-australischer Mineraloge, Petrologe, Geochemiker und Grundlagen-Chemiker, für seine Beiträge zur Mineralogie, insbesondere für die Beschreibung der neuen Mineralien (Kapundait, Mössbauerit, Mojaveit, Bluebellit sowie Favreauit), seine Arbeit an Mineralien der Sapphirin-Supergruppe, Pyrochlor-Supergruppe und Hydrotalcit-Supergruppe und in jüngster Zeit für die Unterstützung der Kenntnis der Kristallchemie von Tellur.
