Top and Bottom Criteria in Structural Geology | Way-Up Indicators Explained with Examples

In this video, we’ll explore one of the most important concepts in Structural Geology — Top and Bottom Criteria, also known as way-up indicators. These are the clues geologists use to determine the original “up” direction of rock layers, even after millions of years of folding, tilting, or overturning! We'll cover: 🪶 What are Top and Bottom Criteria 🪨 Primary Sedimentary Structures (Graded Bedding, Cross Bedding, Ripple Marks, Mud Cracks, etc.) 🔥 Secondary Indicators (Vesicles, Pillow Lavas, Metamorphic Grading) 📍 Field Applications and Mapping Tips ⚠️ Common Mistakes to Avoid By the end of this video, you'll understand how to read the story of Earth's deformation — one rock layer at a time! 💡 Perfect for: Geology students, civil engineers, earth science educators, and anyone curious about how geologists decode Earth’s history.
