This guide covers the geology, composition, formation history, and water/mineral resources of planets and asteroids within our solar system. Tips:
1) Using keywords like "planetary", "extraterrestrial" or "asteroid," will help keep your search off Earth. "Astrogeology" and "exogeology" are also used. Combine with subjects (regolith, volcano, mining, stratigraphy, etc.).
2) Keep checking for new information. Planetary geology and engineering is an evolving field.
3) Does your subject cross disciplines? Consider searching the literature of chemistry, engineering, mining.
4) Having trouble finding a specific publication? Check with a librarian--Some works (conference proceedings, government reports, etc.) can be difficult to discover.
