Volume 27 of Reviews in Mineralogy provides a background to the TEM as a mineralogical tool to
give an introduction to the principles underlying its operation and to explore mineralogical
applications and ways in which electron microscopy can augment our knowledge of mineral
structures chemistry and origin. Much time will be devoted to mineralogical applications. It
provides sufficient information to allow mineralogists and petrologists to have an informed
understanding of the data produced by transmission electron microscopy and to have enough
knowledge and experience to undertake initial studies on their own. The opening chapters cover
the principles of electron microscopy and chemical analysis using the TEM while the following
chapters consider mineralogical petrological and geochemical applications and their
implications for both low- and high-temperature geological environments. The Mineralogical
Society of America sponsored a short courses in conjunction with their annual meetings with the
Geological Society of America and this volume represents the proceedings of the eighteenth in
the sequence. This TEM course was convened October 23-25 1992 at Hueston Woods State Park
College Comer Ohio.
