盐类矿石薄片的制备方法在国內外的一些文献中有所论述,但多偏重于钾盐矿石和古老盐矿石;至于第四纪盐湖中常见的芒硝(Na_2SO_4·10H_2O)、苏打(Na_2CO_3·10H_2O)和天然碱(Na_2CO_3·NaHCO_3·2H_2O)矿石薄片制备的方法介绍甚少。这些含水碳酸盐、硫酸盐类矿物加热易失水,通常置放于室內时表面很快风化失水呈白色粉末状,并易溶于水中,因此不易制成薄片。最近我们作了多次实验,取得一些经验,在此作一介绍以供有关人员参考。实验过程中得到中国科学院地质研究所工厂领导的大力支持和安芷生同志的协助,复照组代为摄制照片,內蒙地质局208地质队提供了样品,谨在此一并致谢。
The preparation methods of salt ores are discussed in some literatures at home and abroad, but more emphasis is placed on potash ore and ancient salt ores. As for the common salt samples (Na_2SO_4 · 10H_2O), soda (Na_2CO_3 · 10H_2O) in Quaternary salt lakes, ) And trona (Na_2CO_3 · NaHCO_3 · 2H_2O) ore flake preparation method is poorly understood. These aquatic carbonate and sulfate minerals are easily heated to water loss. When they are placed indoors, the surface is quickly weathering and dehydrating, which is white powdery and easily soluble in water. Therefore, they are not easy to be made into flakes. Recently, we have conducted many experiments and gained some experience. We will make an introduction here for the reference of relevant personnel. During the experiment, the leadership of the Institute of Geology, Chinese Academy of Sciences and the leadership of the factory support Comrade An Zhisheng assistance, rehabilitation group on behalf of the filming photos, Inner Mongolia Bureau of Geology 208 geological team provided a sample, would like to thank here.
