Volume Determinations

Abstract

In this chapter, we want to tackle the problem of estimating the modal composition of a rock from micrographs. We will start with an SEM micrograph of a granitoid rock, acquired under BSE contrast, where the different minerals are discernable on the basis of different gray levels. The micrograph we are going to use is the same one that we have used for segmentation in previous chapters. We will therefore use the segmented images and derive volume estimates from phase maps and grain maps.
