Igneous Minerals and Processes

EART22201 Igneous Minerals and Processes 10 Semester 1 Undergraduate Level 5 Margaret Hartley Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Middle part of Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 The course investigates the variety of igneous rock types observed on Earth, and the processes that form them. It covers magma generation in the Earth, differentiation processes, and the links between magma compositions and tectonic setting. It examines the chemical and optical properties of the silicate minerals that make up common igneous rocks. It explains how to use practical, analytical, graphical and theoretical techniques to understand and model a variety of igneous processes, and hence interpret the origin of igneous rock samples. This unit provides the foundations for interpreting igneous rocks encountered elsewhere in the degree programme.

This unit provides the foundations for interpreting igneous rocks encountered elsewhere in the degree programme.  The aims of this course are:1. To provide a systematic overview of the petrological and chemical characteristics of the rock-forming silicate minerals that commonly occur in igneous rocks;2. To explain the melting and crystallization processes that produce the diversity of igneous rocks observed on Earth.You will learn polarised light microscopy techniques to recognise the optical properties of minerals in thin section, and hence characterize the mineralogies and textures of major igneous rock types. You will investigate the diversity of igneous rock types produced in different tectonic settings, and examine how geochemical and mineralogical data are used to interpret melting and crystallization processes.    <table border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td colspan="2" style="width: 496px"> On the successful completion of the course, students will be able to: </td> <td style="width: 72px"> Developed</td> <td style="width: 66px"> Assessed</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 1</td> <td style="height: 1px; width: 432px"> Describe the structure and crystal chemistry of key igneous rock-forming mineral classes</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px">  </td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 2</td> <td style="height: 1px; width: 432px"> Use a polarizing light microscope to identify and characterize key rock-forming silicate and non-silicate minerals from their optical properties</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> X</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 3</td> <td style="height: 1px; width: 432px"> Relate the optical properties of minerals in thin section to their crystal chemistry and atomic structure</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> X</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 4</td> <td style="height: 1px; width: 432px"> Classify igneous rocks using mineralogical and chemical classification schemes</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> X</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 5</td> <td style="height: 1px; width: 432px"> Interpret the formation and history of igneous rocks using observations from thin sections and hand specimens</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> X</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 6</td> <td style="height: 1px; width: 432px"> Describe and explain the processes responsible for producing the diversity of igneous rock types, using natural and theoretical examples</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> X</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 7</td> <td style="height: 1px; width: 432px"> Describe and explain the igneous rock types generated in different tectonic settings</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> X</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 8</td> <td style="height: 1px; width: 432px"> Solve mineralogical and igneous petrological problems by applying numerical and graphical methods to real geochemical datasets</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> X</td> </tr> <tr> <td style="height: 1px; width: 64px"> ILO 9</td> <td style="height: 1px; width: 432px"> Convey key mineralogical and textural features of an igneous thin section using labelled sketches and diagrams</td> <td style="height: 1px; width: 72px"> x</td> <td style="height: 1px; width: 66px"> x</td> </tr> </tbody> </table>   The course investigates the variety of igneous minerals and rocks observed on Earth. Students will use fundamental concepts of crystal chemistry to develop their understanding of the structure and chemistry of common igneous rock-forming minerals. Concepts such as solid solution, phase transitions and exsolution will be explored using graphical methods including binary phase diagrams. They will learn about magma generation and crystallization in the Earth, eruption and intrusion processes, and the links between magma composition, mineralogy, and tectonic setting. Each week consists of 1-3 short asynchronous videos, followed by a 1-hour synchronous classroom session and 2-hour practical.E-learning materials:- Online quizzes (1 per week; not assessed; formative feedback given at the end of each question; can be attempted multiple times)- The content of each week’s lesson is provided as short (~10 minutes) videos- All lecture and practical materials are provided as downloadable files- Reading list with links to Library resources, online mineral and thin section gallerie  0 Other 30% 1 Written exam 70%   <table border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td style="height: 68px;
