Explore sedimentary structures in this comprehensive petrology lecture. Delve into the classification of inorganic, primary (physical), secondary (chemical), and organic (biogenic) structures. Learn about bedding geometry, lamination, and the significance of various sedimentary features in determining paleoenvironments and flow directions. Discover how trace fossils can be used to define major facies belts and determine stratigraphic order in overturned sequences. Gain valuable insights into sedimentology principles and their applications in geological studies. Suitable for undergraduate and postgraduate geology students, this 28-minute video is part of a 16-week, 4-credit course taught by Dr. Harel Thomas, Professor of Applied Geology at Doctor Harisingh Gour Vishwavidyalaya.
