Minerals Under the Microscope

Synopsis: First shows a large-scale polarising microscope, demonstrating the principles of optical mineralogy and includes animation about light polarisation and interference. Then shows the preparation of rock thin sections, some of which examined using a microscope. Explains how it is possible to identify mica, pyroxenes and feldspars in real rocks even when the minerals have been cut in a variety of directions.
