PetDB is a scientific information system that maintains a geochemical data collection of ocean floor igneous and metamorphic rocks. PetDB contains analytical data (major oxides, trace elements, stable and radiogenic isotope ratios, analytical ages) for whole rocks, volcanic glasses, minerals, and melt inclusions for samples from mid-ocean ridges, fracture zones, back-arc basins, young near-ridge seamounts, and old oceanic crust. The majority of the data are for mid-ocean ridge basalts (MORB) and abyssal peridotites.
