Looking for information on the makeup of North Atlantic seafloor rocks? How about the composition of volcanic deposits in the Galápagos Islands? Bore into GEOROC, a geological chemistry database hosted by the University of Mainz in Germany. GEOROC's creators gleaned from the literature chemical measurements for nearly 100,000 igneous rock samples collected from the ocean floor and from islands around the globe. The site provides concentrations of common and trace elements and of radioactive isotopes, and you can customize your search by element, location, and type of formation.
