n.硫化铁矿
This paper deals firstly with the distribution of pyrites in coals. 首先揭示了煤中黄铁矿的分布赋存规律。
Its gold content is closely related to pyrites and arsenopyrite. 矿石中的金以不可见金为主,含量与黄铁矿、毒砂关系密切。
It's a new-geochemical method,which gold deposits are surveyed with pyrites. 利用黄铁矿进行找金是一种新的地球化学找矿方法。
An early hypothesis by Chakraborti holds that the arsenic is associated with iron pyrites and enters the aquifers by an oxidation process. 加卡波狄较早提出的一个假说认为，砷与黄铁矿结合并透过氧化作用进入含水层。
We utilized the change of concentration ratio between pyrites and rocks to survey gold deposits. 所以通过金在黄铁矿及岩石中浓度比值的变化，能有效地指导勘查金矿床。
