The Rock Property Catalog is an online database of the petrophysical properties of rocks and minerals. The records in the database are stored in this wiki, in the RPC namespace. The rocks are also all members of Category:Rocks.

You can use the data for whatever you want. Please credit the original publisher of the data by citing it as you would any other scientific data. If you use the data en masse, please link to this page which explains the provenance of the data.

Querying the database

You can query the catalog in various ways, either via the wiki or via the web API. Let's say we want to find shales with a velocity over 5000 m/s. You have a few options:

  • Go to the semantic search form and type [[lithology::shale]][[vp::>5000]]
  • Make a so-called inline query on your own wiki page (you need an account for this). There are examples on the Example RPC queries page.
  • Make a query via the web API with a rather long URL, e.g.
http://www.subsurfwiki.org/api.php?action=ask&query=[[RPC:%2B]][[lithology::shale]][[Vp::>5000]]|%3FVp|%3FVs|%3FRho&format=jsonfm

For example, here are the rocks that I originally started the catalog with:


This is the query that generated that table:

{{#ask:[[Citation::Castagna and Swan 1997]]|?Description|?Vp|?Vs}}

You can also make a link to a CSV file with this data: CSV

Data source

All of the rocks have a reference, which is the canonical source of data for that rock. The data in the catalog were initially from two major sources:

  • Mudrock Anisotropy database, aka Mr Anisotropy, a public domain database curated by Steve Horne. It contains over 1000 records of mudrocks, gathered from the literature.
  • Common Ground, a public domain database collected by John A. Scales, Hans Ecke and Mike Batzle at Colorado School of Mines in the late 1990s, is now defunct and has been officially discontinued, as of about two weeks ago. It contains over 4000 records, and is public domain. The trouble is, you have to restore a SQLite database to use it.

The data have since been augmented by rocks from some other sources.

License

The data is probably best described as public domain. This manifestation of the data is offered under the same CC-BY terms as the rest of SubSurfWiki. This means that Agile Geoscience is not responsible for what you do with the data, or for errors it contains. If also means you can use the data for whatever you want, without permission.
