Module summary

An introduction to chemical processes in the Earth in terms of the geochemical cycles affecting the atmosphere, surface waters and sediments; its overall composition; and its origin and chemical evolution. Topics covered include: Geochemical cycles in the atmosphere, hydrosphere, lithosphere and biosphere (including the carbon cycle); Box modelling of geochemical cycles; Chemical processes occurring during the major geochemical cycles and how these effect the atmosphere, surface waters, sediments and deep earth fluids; Principles of radiogenic and stable isotopes as geochemical tracers, geochronology; Earth and solar system chemical evolution.This module is taught in semester 1 through lectures with some paper based practicals, and is assessed via two online VLE MCQ tests and a one and a half hour final examination.

Objectives

On completion of this module, students will have developed an understanding of the chemical processes which influence our environment and have influenced the evolution of the Earth over time, and an appreciation of the methods by which this knowledge has been obtained.

This module will consider the chemical behaviour in and between gases, aqueous solutions, solids and melts, and how chemical processes involving these components have operated on timescales from a human lifetime to the age of the solar system. Students will also learn how the 'earth-air-water factory' operates at present and to set this in the context of long-term geochemical evolution over the 4.5 Ga of Earth history.

Syllabus

Geochemical cycles overall including the oxygen, water and carbon dioxide cycles;
Chemical processes in geochemical cycles;
Chemistry of surface waters;
Chemistry of deep Earth fluids;
Radiogenic isotopes;
Isotope tracers;
Stable isotopes in geochemistry;
Earth and planetary evolution;
Chemical evolution of the Earth.
