greenockite

1.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.

在贵州牛角塘锌矿床中既有生矿存在,也发现了原生矿。

2.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矿中,少量以矿等独立矿物形式存在于矿床氧化带，是风化淋滤过程中形成生矿物。
