Department: Earth Sciences

GEOL3011: Petrology, Geochemistry and Global Tectonics (Fieldwork)

Prerequisites

• GEOL1051 Field Studies and GEOL2231 Igneous and Metamorphic Geochemistry and Petrology.

Corequisites

• None.

Excluded Combination of Modules

• None

Aims

• Explore the primary control subduction exerts on global geochemical cycles and the creation and destruction of Earth's crust
• Understand the changes to the oceanic crust from ridge to subduction
• Critically appraise geochemical data from primitive basalts for application to aspects of subduction and melt generation
• Apply petrographic and geochemical data to case studies of arc magmatism and interpret results
• Evaluation of geochemical data to understand the processes and timescales of Earth's formation, and the evolution of the mantle and crust over Earth's geological history

Content

• Understanding dynamic Earth systems.
• The drivers of global Earth processes.
• The relationship between interior and exterior processes.
• Integrating petrologic, geochemical and tectonic information to evaluate magma generation.
• Understanding the geochemical evolution of the Earth

Learning Outcomes

• Evaluation of observational evidence for solid Earth processes and driving mechanisms.
• Subject knowledge and understanding of the primary control subduction exerts of global geochemical cycles.
• Subject knowledge and understanding of the structure, composition and history of the Earth and how these vary over geological timescales.
• Subject knowledge of the uses and limitations of isotopic applications in the sold Earth and arc systems.
• Subject-specific knowledge of the history and role of the International Ocean Discovery Program
• Subject-specific knowledge of the definition, use and measurement of oxygen fugacity
• Subject-specific knowledge on the use of short- and long-lived isotopes to understand Earth's formation and differentiation.

• Intellectual and practical skills to apply geological principles and methodologies to the solution of familiar and unfamiliar problems.
• Intellectual and practical skills to critique and test existing hypotheses.
• Intellectual and practical skills to synthesise information/data from a variety of sources.
• Intellectual and practical skills to analyse, evaluate/interpret geological data.

• Student's experience and expertise will be improved through:-
• Discipline skills developed through the taught material and practical exercises.
• Interpersonal skills in class sessions including small group work and presentation skills.
• Problem solving in class.
• Field trip (to the Alps or Iceland):-
• Understand the geological history as recorded in the sedimentary, metamorphic and igneous rocks.
• Understand the broad tectonic controls on the formation of the Alps or Iceland.
• Produce an observation-based assessment of one aspect of Alpine or Icelandic geology.

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

• The module is delivered through 2 terms of research-led teaching, delivered in 3 hour blocks which comprise a mixture of lectures and practicals, formative exercises, group discussions and directed reading through which students learn about Earth processes and driving forces and acquire skills.
• Guidance on preparation, key and exam skills is provided.

Teaching Methods and Learning Hours

Summative Assessment

Formative Assessment:

Feedback will be given on all practical activities and advice on exam technique given.

■ Attendance at all activities marked with this symbol will be monitored. Students who fail to attend these activities, or to complete the summative or formative assessment specified above, will be subject to the procedures defined in the University's General Regulation V, and may be required to leave the University
