  1. Chapter 7 Reading Quiz Flashcards | Quizlet

    What is the difference between brittle and ductile deformation? Brittle deformation occurs when rocks break; ductile deformation occurs when rocks bend. What structures form as a result of …

  2. CHAPTER 10 (Folds, Faults and Rock Deformation)

    In ductile deformation, a gradually increasing force will cause the rock to undergo smooth and continuous plastic deformation. The rock will contort and change shape without fracturing.

  3. Ductile deformation is when a rock deforms plastically like silly putty (Fig. 7.1B). In this case, features in the rock can change shape without developing visible fractures, and the whole …

  4. Structures 4.2 - Radford University

    Geologic structures are divided into two basic groups, brittle structures and ductile structures. Rocks deformed by fracturing or breaking have brittle structures.

  5. 2.1 Crustal Level: Brittle versus Ductile Deformation‌ – Structural ...

    Metamorphic foliations and tight folds are ductile structures generated at great depths; they are the oldest in the deformational history of the rocks. They are not by themselves relevant to …

  6. 7.7: Geologic Structures - Geosciences LibreTexts

    Deeper in the crust, where the rocks are more ductile, folding happens more readily, even when the stress and strain occurs rapidly. The most basic types of folds are anticlines and synclines. …

  7. Ductility (Earth science) - Wikipedia

    Ductile deformation is typically characterized by diffuse deformation (i.e. lacking a discrete fault plane) and on a stress-strain plot is accompanied by steady state sliding at failure, compared …

  8. Deformation – A Brief Introduction to Geology and Geomorphology

    Rocks will deform in brittle or ductile manner in response to the tectonic forces acting on them. Brittle deformation means the rock cannot accommodate a force by flowing but will instead …

  9. Reading: Folds | Geology - Lumen Learning

    Folds often form during crustal deformation as the result of shortening that accompanies orogenic mountain building. In many cases anticlines are formed by movement on non-planar faults …

  10. Overview of Folds, Faults, and Unconformities

    Folds are geologic structures created by ductile (plastic) deformation of Earth’s crust. To demonstrate how folds are generated, take a piece of paper and hold it up with a hand on …
