The Mineralogical and Geological Museum at Harvard University (MGMH) holds vast geological collections that have been assembled since the late eighteenth century. They are a legacy of vigorous research and teaching in various fields of geology including mineralogy, petrology, and mining geology.
The museum serves as a repository for more than 400,000 specimens of minerals, rocks, meteorites, and gems. Samples range from display to reference quality and represent a broad range of species and localities from around the globe. Particular strengths of the collection encompass material from the New England region and over two hundred type mineral specimens.
Although fossils are critically important geological specimens, at Harvard University they are housed with the biological collections. Fossil plants are held by the Harvard Herbaria and fossil animals are held by the Museum of Comparative Zoology.
