Maps and Landscape / Earth Materials

S260 support video in four bands:
1) Geological Time: Shows how the rock record relates to time, and illustrates the law of superposition and the law of faunal succession. Demonstrate the immensity of the geological timescale and discusses the contribution of William Smith in correlating strata and producing the first detailed geological map of England. Examines indicator fossils, the concept of unconformity, and radiometric dating.
2) Geology and Landforms: In three parts: 1) on Skye, shows landforms including plateau basalts, gabbros, granites and sediments, and explains the relationship of each landform with its underlying geology; 2) explains an associated CD-ROM which includes a virtual field trip to Skye; 3) views Dorset landscape scenery to show the relationship of the underlying geology - Jurassic and Cretaceous sediments - to the related landforms.
3) Using the Microscope: how to use the petrological microscope that is included in the course materials. Demonstrates the operation of each part of the microscope and then shows a series of minerals and the way they can be examined in plane polarised light and between crossed polars. The minerals include biotite, muscovite, microcline, plagioclase and orthoclase feldspar and quartz as constituents of granite; olivine, pyroxene, amphibole and garnet as they appear in thin section as constituents of other rocks; also calcite as it occurs in marble.
4) Rocks in the Field: Discusses rock classifications - igneous, sedimentary and metamorphic - and examines rocks in each category at various locations along the coast of County Antrim in Northern Ireland.
