LECTURE series: SGL 201 Principles of Mineralogy. 63 LECTURE 4 INTRODUCTION TO THE MICROSCOPIC STUDY OF MINERALS LECTURE OUTLINE Welcome to the fourth LECTURE of this unit. You should now be familiar with the concepts of optical mineralogy covered in LECTURE 3. In this LECTURE , we are going to learn firstly about the important components of the petrographic microscope itself. Technologically, microscopes vary in their design, not only in their appearance but also in the positioning and operation of the various essential components.
