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.

在贵塘锌矿床中既有次生硫矿的存在,也发现了生硫矿。

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.

主要类质同象存在于闪锌矿中,少硫矿等独立矿物形式存在于矿床的氧化带，是风化淋滤过程中形成的的次生矿物。
