The electron and other physical properties, distinguishing features and probe and other analytical instruments have become paragenesis. Important correlations between these more widely employed, but in our view this does not aspects of mineralogy are emphasized wherever possible, diminish the importance of the petrological polarizing and the content of each section has been updated where microscope which provides an overview of the minerals needed in the light of published research over the and their relationships as they occur in rocks before they 21 years between editions.
