Discovery Series Tutorials 10 & 15

Over the years our geosciences community has proven that when we navigate challenging times together, we emerge more resilient than before. Use this time to hone your knowledge and skills to help prepare for the now, the next, and the new normal.


Courtesy of AAPG and AAPG Datapages, two Discovery Series data sets have been donated at no charge for use as online teaching materials. Discovery Series 10 – Sandstone Petrology: A Tutorial Petrographic Image Atlas 2nd Edition and Discovery Series 15 – Carbonate Petrology: Interactive Petrography Tutorial, both authored by Kitty Milliken, have been posted online for easy accessibility.


Discovery Series 10

This tutorial offers the beginning student of sedimentary petrology an overview of the major constituents of sandstones as seen, primarily, through the petrographic microscope. The focus is on the practical aspects of constituent identification and interpretation.
