Using EarthChem Portal to create an Integrated Data Table
EarthChem's web portal offers access to geochemical data in federated geochemical databases, including PetDB, GEOROC, NAVDAT, SedDB, the Deep Lithosphere Dataset, the USGS National Geochemical Database, MetPetDB, and the GANSEKI database. This page explains how to extract an integrated table of your desired geochemical data. The two main steps to getting your integrated dataset are:
1. Constrain Sample selection
Sample selection is set on the Portal Search page.
The sample selection can be constrained by:
2. Choose the data display and geochemical parameters
Once you have set all of the constraints on the samples, click “Continue to Data Selection.” You will see a number of different options for accessing the data, metadata, and visualizations. For more information on the visualization tools, see the page on additional EarthChem Portal features.
To proceed to the integrated dataset, click on the first option “Get Chemical Data.” You will see a list of the chemical parameters stored in the EarthChem Portal, grouped by type (Major Oxides, Isotope Ratios, Rare Earth Elements, etc.)
You may customize your output table by setting the following options:
Finally, click the Go To Data button. The click will either display the HTML page or download the .txt or .xls to the default location in your local machine.
