CHEMICAL ANALYSIS OF MINERALS

SPECTROSCOPIC TECHNIQUES There are multi lltiple types of spectitroscopic thitechniques th tthat can be used to study the characteristics of elements that compose minerals. For the most part, all spectroscopic techniques take advantage of the same energy principals: 1) By bombarding a sample with energy, electrons and/or
