Teaching Resources

Advice and links for teachers and students

Students

The Open University has created a free course on the OpenLearn website, which can be used in conjunction with the VM teaching collections.

You can learn how the polarising microscope works and how to identify minerals and rocks under the microscope in the free OpenLearn course introduction to mineralogy and petrology. These resources represent adapted extracts from a Level 2 Open University geology module, and include:

  • minerals in the crystalline state, states of matter, physical properties of minerals in hand specimen, the atomic structure of crystals, crystal defects and twinning, and crystal symmetry and shape 
  • minerals and the microscope including: the nature of light, minerals and polarised light, minerals and the polarising microscope.

The OpenLearn course includes many activities that use the virtual microscope – helping you to learn the characteristics of minerals and rocks in thin section.

Useful resources

Guide to Thin Section Microscopy by Raith, Raase and Reinhardt (2012) is a complete and detailed guide to the study of minerals and rocks using a polarising microscope. It is freely available on the Open Access Publications section of the Mineralogical Society of America website, along with several other interesting publications.

Handbook of Mineralogy presents >4000 separate pdfs, each with optical, textural and chemical information on a particular mineral species. These are also hosted on the Mineralogical Society of America website.

This Atlas of Metamorphic Minerals on the Oxford University website features thin section images of many common metamorphic minerals.
