One of the missions of the AMNH is to curate scientific collections, and among these is the petrology collection, for which I am ultimately responsible. The main strengths of this collection are in mantle materials and layered intrusions. A number of colleagues, including Tony Morse, Valeri Federenko, Gerry Czamanske, Alexander McBirney and Emil Jagoutz, have recently donated all or parts of their collections. The collection also includes drill core from the Hawaiian Scientific Drilling Project (HSDP). An on-line version of the catalogue is available here.
Samples from the collection are freely available for valid research purposes. Please send requests to me or to Njoki Gitahi, the collections manager.
