CO3DB — The Digital Carbonate Database

Hasiuk, Franciszek

It has become increasingly difficult for the student (or even the seasoned researcher) to keep up with the vast volumes of new primary literature being generated each year. Even the most diligent researcher usually only compares their data to only a few other datasets that they deem analogous. The CO3DB is a growing on-line database of published carbonate geochemical and petrophysical data meant to address this problem. By querying this database and comparing their data to the results, a researcher can be reasonably confident that they have compared their data to "the literature."

CO3DB is divided into three parts. The first is a database of all articles in journals that have a history of printing carbonate data (e.g. Journal of Sedimentary Research, AAPG Bulletin, Geochimica et Cosmochimica Acta, Chemical Geology, Carbonates and Evaporites, GSA Bulletin, Geology, Science, Nature). Each article has been noted for the presence carbonate geochemical and petrophysical data (e.g. mineralogy, elemental and isotopic data, porosity, permeability, SEM and thin section images) as well as other geological data (e.g. age, formation, location, taxon). This functionality allows researchers to quickly identify comparable data such as "stable isotope data from the Triassic of Italy" or "thin section images of radiaxial cement." Hyperlinks then point researchers to the original articles.

The second phase of CO3DB development is to bring carbonate geochemical (e.g. δ13C, δ18O, Mg/Ca) and petrophysical (e.g. porosity, permability, Vp) data directly into its structure. This has been done so far for SEPM's Journal of Sedimentary Research. Future data will be added as entire journals from the above list are mined. A third phase, in preliminary development, will allow on-line production of publication-quality graphs of geochemical and petrophysical data as well as on-the-fly units conversion (e.g. ppm to atom ratio).

Meta-analysis of CO3DB data is also possible. For example, the relationship between Mg/Ca and Sr/Ca in the three major carbonate minerals (calcite, dolomite, and aragonite) is elucidated in greater detail using a larger database of analyses.
