Petrography is a branch of petrology that focuses on detailed descriptions of rocks. Someone who studies petrography is called a petrographer. This course is designed to help the students to identify the minerals in sedimentary, igneous and metamorphic rocks using a polarizing microscope and also classifying the rocks on the basis of rock texture and mineral composition. The mineral content and the textural relationships within the rock will be 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 a 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 is critical to understanding the origin of the rock.

  1. To help students understand the microscopic details of sedimentary, igneous and metamorphic rocks.
  2. Secondly, to guide students to decipher the texture, mineral composition,  micro-texture and structure of various rock types under the thin-section.

    Learning Outcomes:

  • This course is designed to acquire the knowledge about the description of various types of rocks and minerals.
  • This will help the students to understand the microscopic world of mineral composition, texture, and structure.
