PETDB: Petrological Database of the Ocean Floor

Columbia University, LDEO

This web page provides an interactive petrological database of the ocean floor. The ultimate goal is to provide a robust, complete reference data library for the petrology and whole earth science communities. Users enter search parameters such as geographical name, latitude, longitude, elevation, tectonic setting, expedition name and chemistry, and receive information on the petrological condition of that area. Data received included the rock type, alteration, sampling technique, tectonic setting, and location.
