The Petrology Lab is the Department of Earth Science's focal point for understanding problems concerning the chemical evolution of minerals and rocks. Microscopy is an important tool in understanding the reactions involved. Leitz Ortholux and Dialux petrographic microscopes are available. An Olympus BHS and Zeiss research polarizing microscope equipped with 35mm or Polaroid cameras can be used to obtain images of thin sections. The petrology lab also houses a computer controlled MicroMill System for precise sampling of thick sections by a drill mounted on a video microscope assembly. This sampling allows traverses for oxygen isotope and XRF analysis to be made across a mineral.
