盐间非砂岩样品的化学分析方法

Chemical Analysis Method of Intersalt-bed Non-sandstone Samples

盐间非砂岩样品的化学分析方法是一种对可溶性矿场离子进行分析的方法。它能够定量分析可溶性矿物离子的绝对含量和水不溶物与酸不溶物的含量，为了解盐类岩石的矿物共生组合及每种矿物的百分含量，准确确定岩石的定名和矿床成因类型提供依据。在使用该方法时，要严格按技术要求准备样品的制备和溶样，准确掌握溶解作用对溶样的影响；采用离子色谱仪对可溶性矿场离子进行检测，将滤液稀释5～10倍。

Chemical analysis method of intersalt--bed non--sandstone samples can be used to quantitatively analyze the absolute content of the soluble mineral ions and the content of non--water soluble and non--acid soluble substance, which can provide the evidences for understanding the coexisting mineral association of salt rock and the percent content of every kind of minerals and for accurately determining the rock name and the genetic types of mineral deposits. While analyzing by this method, we must prepare samples and solution samples, strictly according to technical requirar,~ts, accurately grasp the influence of solvability on solution samples, test soluble mineral ions with ionic chromatography instruments and dilute filter liquor to five to ten times.
