greenockite

It is thought that greenockite is a seconday (supergenic) mineral, but there has been found primary greenockite in the Niujiaotang cadmium-zinc deposit in Guizhou.

在贵州牛角塘锌床中既有次生存在,也发现了原生。

There are some independent minerals of Cd, which are secondary minerals formed during weathering and leaching, such as greenockite, otavite and oxides of Cd in the oxidized zone of the deposit.

主要以类质同象存在于闪锌中,少量以等独立物形式存在于床氧化带，是风化淋滤过程中形次生物。
