Department: Earth Sciences

GEOL3091: DEFORMATION PROCESSES IN THE LITHOSPHERE

Type Open Level 3 Credits 20 Availability Available in 2018/19 Module Cap Location Durham

Prerequisites

  • GEOL2231 Igneous and Metamorphic Geochemistry and Petrology AND GEOL2011 Structural Geology and Tectonics

Corequisites

  • None.

Excluded Combination of Modules

  • None.

Aims

  • To understand the nature, causes, controls and interactions of grain-scale deformation processes within the Earth’s lithsophere and how these are assessed and measured by geoscientists.

Content

  • DEFORMATION PROCESSES
  • Fracturing and fracture process zones.
  • Crystal plasticity, diffusive mass transfer.
  • Practical interpretation of microstructures in rocks.
  • Deformation mechanism and regime maps.
  • Heterogeneity.
  • Fault zone weakening.
  • ROCK, FAULT AND EARTHQUAKE MECHANICS
  • Principles of rock, fault and earthquake mechanics.
  • Deformation experiments and estimating the rocks physical and mechanical parameters.
  • Mechanics and deformation mechanisms of active fault zones: creeping vs. seismic faults.

Learning Outcomes

Subject-specific Knowledge:
  • To systematically describe microstructures and relate these to deformation mechanisms in naturally deformed rocks.
  • To understand how grain-scale processes in the crustal and manle lead to shear localization and weakening behaviours.
  • To understand the relationships between grain-scale deformation mechanisms and seismogenesis in upper crustal fault zones.
Subject-specific Skills:
  • Will have acquired intellectual and practical skills necessary to plan, conduct and report on laboratory projects.
  • Will have acquired intellectual and practical skills in order to apply geological principles and methodologies to the solution of familiar and unfamiliar problems.
  • Will have acquired intellectual and practical skills to observe, record accurately and account for geological features in the laboratory.
  • Will have acquired intellectual and practical skills to synthesise information/data from a variety of sources.
  • Will have acquired intellectual and practical skills to analyse, evaluate/interpret geological data.
  • Will have acquired intellectual and practical skills in citation and appropriate use of the literature.
Key Skills:
  • Critical analysis, research capability: Receive and respond to a variety of information sources.
  • Practical competency: Prepare, process, interpret and present data using appropriate qualitative and quantitative techniques and packages.
  • Independent learning, numeracy, IT skills, information skills, literacy.
  • Initiative and drive, innovation and creativity, problem solving.

Modes of Teaching, Learning and Assessment and how these contribute to the learning outcomes of the module

  • The module is delivered through a mix of one hour-lectures and two-hour practicals, supported by handouts, directed reading and web-based materials held on DUO.
  • The practicals form an important component of the module allowing hands-on learning and experience of tackling and solving graphical-and-thin-section-based problems that help re-enforce key concepts introduced during lectures.
  • Formative assessment is provided in practical tests with feedback.
  • Guidance on preparation, key and exam skills are provided.
