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.

贵州牛角塘锌矿床中既有次生硫矿,也发现了原生硫矿。

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.

主要以类质于闪锌矿中,少量以硫矿等独立矿物形式于矿床氧化带，是风化淋滤过程中形成次生矿物。
