由于气相色谱对H2的检出灵敏度特高，可作为对菱铁矿中含有羟基结构的微量粘土及其矿物杂质的检测方法，反之亦然。

The gas chromatography has extremely high sensibility to identify H_2 , so it is a method to detect siderite which contains micro clays and impurity minerals with OH groups , vice versa .

δ13C的变化情况表明，菱铁矿结核可能形成于硫酸盐还原带。

Such a δ 13 C variation implies that this siderite concretion might have been formed in the sulphate reduction zone .

菱铁矿的形成与H2障有关；铅、锌等硫化物的就位主要与H2S障或H2障的配合作用有关。

The formation of siderite is related to the H_2 barrier , while the emplacement of lead and zinc sulfides bears a relation mainly to H.S barrier or the combined action of H_2S and H_2 barriers .

从测得的DTA/EGD/GC曲线所提供的信息和数据表明：菱铁矿中含有微量高岭土，则在热分解逸出气的GC谱图中就有H2峰出现。

The information and data supplied by the detected DTA / EGD / GC curves shows : if the siderite involves micro kaolinite , H_2 peak will appear on the GC profile of the evolved gas of the thermal decomposition .
