The Petrological Database of the Ocean Floor (PetDB) is a comprehensive scientific database that archives and disseminates data on the mineral and chemical composition of oceanic rocks, as well as related geological information. It primarily focuses on igneous and metamorphic rocks collected from the ocean floor, including mid-ocean ridges, ocean islands, and seamounts.
