Favorite Astro Plots: The Pyroxene Quadrilateral

Melissa Lane • June 15, 2018

Petrology is a field of science in which scientists study the compositions of rocks and minerals and interpret their geologic history. A common graph petrologists use is the “pyroxene quadrilateral.” These graphs, like photos of space, can reveal an understanding of the remotest parts of the solar system.
