How to Cite EarthChem Data

Synthesis Databases

To cite a synthesis database or portal, please reference the its URL in text and in figure captions:

Please cite the specific download from PetDB (or SedDB) by giving the date and, if possible, parameters of the download. Here is an example for PetDB:

"The data were downloaded from the PetDB Database ( on 31 August, 2016, using the following parameters: feature name = Gakkel Ridge and rock classification= basalt."

In addition, you should also cite the original scientists who contributed to the downloaded dataset. We also strongly encourage that you create a secondary bibliography for work that uses large datasets. You can easily download all of the references that contributed to a dataset for this secondary bibliography. Many journals will accept a secondary bibliography as a supplementary material file, and this type of citation helps ensure that the hard work performed by members of our community is acknowledged properly.


For PetDB, you may also add the following publication in the reference list:

Lehnert, K., Su, Y., Langmuir, C., Sarbas, B., & Nohl, U. A global geochemical database structure for rocks. Geochem. Geophys. Geosyst. 1, doi:10.1029/1999GC000026 (2000)


For SedDB, you may also add the following publication in the reference list:

Status Report on the SedDB Sediment Geochemistry Database: March, 2012. Johansson, A., Lehnert, K, and Hsu, L. GeoPRISMS Newsletter No. 28, Spring 2012, p. 21.




EarthChem Library


When citing data obtained from the EarthChem Library, we ask that you cite the dataset with its dataset DOI (if applicable), and note that it was obtained from the EarthChem Library.


It is also best practice to cite any primary publication that originally published the dataset, if one exists and is mentioned in the EarthChem Library record.


e.g. Shaw, Alison, Gakkel Ridge basalt melt inclusion and mineral chemistry,  doi:10.1594/IEDA/100004, obtained from the EarthChem Library (


Shaw, A. M., M. D. Behn, et al. (2010). "Deep pooling of low degree melts and volatile fluxes at the 85 degrees E segment of the Gakkel Ridge: Evidence from olivine-hosted melt inclusions and glasses." Earth and Planetary Science Letters 289(3-4): 311-322.
