DataSet Source



Normalized Spider Diagram. This page will scale and plot geochemical data from pre-selected datasets or from a dataset that you upload using the spider element selection of Thompson and others (1984).

Use the Normalizing Composition pulldown list to choose the normalizing composition.

Normalizing compositions from the following sources are available: McDonough and Sun (1995), Gale and others (2013), and Thompson and others (1984).

To view other DataSets choose a DataSet Source of preformatted DataSets by selecting from the pull down list. Then choose from among the preselected DataSets from the pull down list. You can upload your own data from a comma separated value file (.csv) if the first row of the file has the oxide and element labels, and subsequet rows have sample data.    

Preselected datasets are available from:
PetDB (Compiled and Maintained by EarthChem at Lamont-Doherty)
GEOROC (Compiled by the Max Planck Institute for Chemistry in Mainz)
PETROS Igneous Rock Database (Compiled by Felix Mutschler at Washington State University)
Ueki, Hino, and Kuwatani (2018) (Data compiled from PetDB and GEOROC)
