About PetDB Data

PetDB contains geochemical data from sub-oceanic igneous and metamorphic rocks generated at mid-ocean ridges including back-arc basins, young seamounts, and old oceanic crust compiled primarily from the published literature.

Analytical Data

PetDB accommodates the full range of analytical values, from major and trace element concentrations to radiogenic and stable isotope ratios, in volcanic glasses, whole rock samples, minerals and melt inclusions..

Metadata

PetDB contains abundant information about the analytical procedure and data quality (method, precision, standard measurements), and a wide range of contextual information about the samples (rock type, texture, age, modal composition, alteration), sample locations (geospatial coordinates, location names, tectonic setting) sampling process (technique, date, cruise), analytical procedures and the source of the data (references, authors).
