The Division of Mineralogy and Meteoritics oversees a historically important worldwide collection of over 40,000 mineral specimens catalogued into a systematic collection created from the original Yale Peabody Museum holdings and the G. J. Brush Mineral Collection. The collection includes 36 documented type specimens, as well as other presumed type specimens that require further documentation.

The largest and most important mineral collection in the Division is the G. J. Brush Mineral Collection. Other collections include the Blum Collection of pseudomorphs and the Lazard Cahn Collection of micromounts.

 

In addition to the many referenced specimens, the collection contains suites of material from localities that no longer exist, early prospecting material, a collection of gemstones, and a sizeable collection of Connecticut minerals.

 

The Yale Peabody Museum’s meteorite collection was begun by Benjamin Silliman in the early years of the 19th century with the fall of the Weston meteorite on December 14, 1807, not far from New Haven, Connecticut.

Some of the 30 or so meteorites acquired by Silliman over the next half century came in mineral collections. The Gibbs Collection contained several pieces of the Krasnojarsk pallasite as well as the largest unbroken specimen (36 pounds; 16 kilograms) of the Weston meteorite. The Red River meteorite - the largest acquired by Silliman - is a 1,635-pound (742-kilogram) iron found in Texas in 1808. This massive object is still the largest meteorite in the collection.

 

Today the meteorite collection contains several thousand specimens from over 400 localities worldwide, as well as a representative collection of tektites and other impact-related materials.

 

The Yale Peabody Museum’s collections are available to legitimate researchers for scholarly use. Loans are issued to responsible individuals at established institutions. Loans and access to the collection can be arranged through the Collection Manager.
