粘土矿物广泛分布于各种沉积岩中。由于粘土矿物颗粒细小、常与长石、石英、有机质等混杂在一起,要详细研究粘土矿物,必须首先进行粘土提纯。 粘土提纯的方法有:超速离心机法、静水沉降法、电泳法等。通过我们近二十年来的工作实践,建立了较完善的静水沉降粘土提纯法。本文除着重介绍了这种方法外,并对电泳法也作简单介绍。 粘土矿物一般集中在颗粒粒径<2μ的部分中。运用斯托克斯(Stokes)公式把<2μ部分提取出来。颗粒提取时间参见文献[3]。 我们进行粘土提纯的流程综合如下: 1.取样
Clay minerals are widely distributed in various sedimentary rocks. Due to the small size of clay minerals, often with feldspar, quartz, organic matter and other mixed together to study clay minerals in detail, you must first clay purification. Clay purification methods are: ultracentrifugation method, hydrostatic settling method, electrophoresis and so on. Through our nearly twenty years of practice, established a more perfect hydrostatic settling clay purification method. In addition to highlighting this method in addition to this, and electrophoresis also made a brief introduction. Clay minerals are generally concentrated in fractions <2μ particle size. Use the Stokes formula to extract the <2μ portion. Particle extraction time see [3]. The process for our clay purification is summarized as follows: 1. Sampling
