Quantitative WDS Analysis of a Contact Metamorphosed Calc-Silicate Rock

  • Introduction

    Rocks are not simple materials but are an agglomeration of different chemical compounds or minerals. The formation mechanism and environment can determine the type, shape and distribution of minerals in the agglomerate. Understanding the chemical compositions of the minerals in metamorphic rocks is vital to determining the types of mineral and their textural evolution. In a prior Note, the mineral identification and distribution were determined using Energy Dispersive Spectroscopy (EDS). In this Note, Wavelength Dispersive Spectroscopy (WDS) is used to quantitatively measure the elemental composition of each of the identified minerals.
