This page will scale and plot geochemical data from pre-selected datasets or from a dataset that you upload. Mouseover a datapoint for information about the sample. FeO(T) is total Fe recalculated as FeO. Click on a Dataset button to choose one of the following datasets:

You can upload your own data from a comma separated value file (.csv) by clicking on the "Choose File" button. The first row of the .csv file has the oxide and element labels, and subsequet rows have sample data. Your uploaded file will not be passed to the other diagram or map pages, but can be uploaded again on those pages.
