Interpreting the Physical Properties of a Clay Using Microanalysis Techniques

A microanalysis with the scanning electron microscope and energy dispersive X-ray microprobe (SEM-EDS) is used to explain the apparent brittle failure and sensitivity of a clay soil. The electron micrographs produced show concentrations of pyrite crystals interrupting the parallel bedding of the cla...

Description
Summary:A microanalysis with the scanning electron microscope and energy dispersive X-ray microprobe (SEM-EDS) is used to explain the apparent brittle failure and sensitivity of a clay soil. The electron micrographs produced show concentrations of pyrite crystals interrupting the parallel bedding of the clay particles. These fabric modifiers significantly influence the failure mechanisms of the soil. The SEM-EDS microanalysis provides details of the fabric configuration and distribution of chemical species and their association with the soil fabric.
