The information posted at this web site is an update of a booklet composed by Dr. Charles Meyer in 1987 to accompany microscope thin sections made of a carefully selected subset of lunar rocks. This site is not a comprehensive, or even an introductory, treatise on lunar science. It provides only enough information to provide some context for the study of the thin sections that the NASA curator loans to upper division petrography classes. It needs to be supplemented by educational materials of the instructor’s choosing.
NASA has been providing these sets of petrographic thin sections to colleges and universities for over thirty years. Hopefully the students that get to study these precious samples already have vast experience using advanced microscopes to study polished thin sections of a variety of terrestrial samples. And, hopefully, they will closely follow the Precautions section.
