Petrography Petrography Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. The mineral content and the textural relationships within the rock are described in detail. The classification of rocks is based on the information acquired during the petrographic analysis. Petrographic descriptions start with the field notes at the outcrop and include macroscopic description of hand specimens. However, the most important tool for the petrographer is the petrographic microscope. The detailed analysis of minerals by optical mineralogy in thin section and the micro-texture and structure are critical to understanding the
Institute for the Study of Academic Racism Institute for the Study of Academic Racism The Institute for the Study of Academic Racism (ISAR) is an organization that monitors "changing intellectual trends in academic racism, biological determinism, and eugenics."
