Department: Earth Sciences

GEOL4257: The Geochemical Evolution of the Earth IV

Type Open Level 4 Credits 10 Availability Available in 2025/2026 Module Cap Location Durham

Prerequisites

  • GEOL2231 Igneous and Metamorphic Processes

Corequisites

  • None

Excluded Combination of Modules

  • GEOL3467 The Geochemical Evolution of the Earth

Aims

  • To explore the processes and timescales of Earth’s formation, and the evolution of the mantle and crust over Earth’s geological history.
  • Investigate the processes responsible for the formation of the Earth and other planets.
  • Critically evaluate geochemical evidence for the differentiation of the Earth (to form the core, mantle and crust).
  • Use geochemical data to assess the nature and timing of Earth’s differentiation, and the chemical evolution of Earth’s interior over time.

Content

  • Understanding the geochemical evolution of the Earth, to include:
  • Earth’s formation and differentiation
  • Understanding the origin of the Moon and the implications for the Earth
  • Making a habitable planet – Earths water and the late veneer
  • Evolution of Earth’s mantle over time
  • Chondritic Earth, the origin of planetary material
  • Growth and evolution of the continents

Learning Outcomes

Subject-specific Knowledge:
  • Evaluation of geochemical evidence for solid Earth processes and driving mechanisms.
  • Subject knowledge and understanding of the structure, composition and history of the Earth and how these vary over geological timescales.
  • Subject-specific knowledge on the uses and limitations of short- and long-lived isotopes to understand Earth’s formation and differentiation (from core formation to partial melting).
Subject-specific Skills:
  • Intellectual and practical skills to apply geological principles and methodologies to the solution of familiar and unfamiliar problems.
  • Intellectual and practical skills to critically assess and test different hypotheses.
  • Intellectual and practical skills to synthesise information/data from a variety of sources.
  • Intellectual and practical skills to analyse, evaluate and interpret geological and geochemical data.
Key Skills:
  • Student experience and expertise will be improved through;
  • Discipline-specific skills developed through the taught material and practical exercises.
  • Interpersonal skills in class sessions including small group work and presentation skills.
  • Problem solving and critical thinking in class.
  • Acquire skills necessary for self-managed lifelong learning including independent research, critical analysis, and time management.
  • Identify and work towards targets for personal and academic development.

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

  • This module is delivered through one term 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.
  • Practical sessions to promote advanced critical reasoning, scientific research, scientific writing skills, and writing skills.
  • Completion of a research report based on specific aspect of the course content, either relating to one of the weekly themes, or a synthesis of wider aspects of the module.
