Preface

Author (Name, Year)

Mumme & Sparrow & Walker, 1988

Addi­tional Informa­tion

Roxbyit wurde ursprünglich in Kupfer-Erzkonzentraten der Olympic Dam Mine entdeckt. Man fand aber heraus, dass er künstlich durch technische Prozesse in der Erzreduktion entstand. Das Ausgangserz hat das Mineral Roxbyit nicht enthalten.
In der Goldlagerstätte Maikain wurde natürlich vorkommender Roxbyit gefunden. (P. KARTASHOV)
