 Initially developed for PetDB and its subareal counterpart GEOROC, this relational data model has demonstrated utility and flexibility by its application in subsequent geochemical database projects including NAVDAT, MetPetDB, and SedDB

Since its inception, PetDB has supported a wide array of scientific endeavors, providing easy access to a comprehensive global dataset of geochemical data for mid-ocean ridge basalts, abyssal peridotites and also xenolith samples from the Earth's mantle and lower crust.PetDB has been cited in more than 800 peer-reviewed scientific articles as the source of data used to develop and test new hypotheses which range from the chemical and mineralogical composition of Earth's mantle (e.g.Salters & Stracke 2004, Thirlwall et al.
