GEOL3467: Geochemistry of the Earth

• GEOL2231 Igneous and Metamorphic Processes

• None

• None

• To explore the processes and timescales of Earths formation, and the evolution of the mantle and crust over Earths 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 Earths differentiation, and the chemical evolution of Earths interior over time.
• Explore the relationship between continental weathering and tectonics, and ocean chemistry and circulation.

• Understanding the geochemical evolution of the Earth, to include:
• Earths 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 Earths mantle over time
• Chondritic Earth, the origin of planetary material
• Growth and evolution of the continents
• Continents and oceans chemistry and ocean circulation.

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 Earths formation and differentiation (from core formation to partial melting).
• Subject knowledge of the uses and limitations of isotopes to trace weathering and circulation in the oceans.

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.

• 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.
