海泡石粘土矿中的海泡石含量,多依靠x射线衍射分析法或红外吸收光谱法测定。但采用这两种测试手段时,必须先行提取高纯度(>95%)的标样,而且测试费用较高,分析周期较长,因而使地质勘探费用增高,有可能造成探矿工程布设的盲目性。笔者在从事早二叠世海相沉积型海泡石粘土矿的找矿工作时,曾有意识地对不同品位的海泡石粘土矿进行了海泡石含量和饱和 Sepiolite clay mine sepiolite content, and more rely on x-ray diffraction analysis or infrared absorption spectrometry. However, when using these two test methods, high purity (> 95%) standard samples must be taken first, and the test cost is high and the analysis period is long, which increases the cost of geological exploration and may cause the blindness of prospecting engineering layout . The author engaged in the Early Permian marine sedimentary sepiolite clay ore prospecting work, had consciously sepiolite clay sepiolite content and saturation of different grades
