Note(s): The nature of the method of delivery of this course and the field trip and practical work may lead to difficulties for students with some disabilities however all possible alternatives will be investigated. Students with disabilities are highly recommended to seek a meeting with the School Disability Coordinator to discuss this further. This course may NOT be included in a graduating curriculum with GL 1005 and GL 1505.

The rocks, of which the rigid, outer shell of the Earth is made, are themselves composed of a range of different minerals. Igneous rocks, which crystallise from rock melts (magma), contain minerals that reflect the processes operating within and at the margins of the plates that form the rigid shell. Metamorphic rocks are formed in response to the forces associated with the movement of the plates and/or to changes in temperatures. The weathering and erosion of pre-existing rock formations and the transport and deposition of this debris by ice, wind, water and gravity form most sedimentary rocks. However, some sedimentary rocks are mainly of biological or chemical origin (e.g. chalk, rock salt). The composition of, and the mineral associations in rocks are therefore directly related to the processes that formed them. The identification and classification of rocks is therefore a crucial skill in studies relating to the evolution of the Earth.

This course will be delivered independently through WebCT, with an intensive practical weekend.
