Exploration geology/Quiz

Exploration geology is a lecture and an article from the school of geology. It is about finding substances containing the various valuable mineraloids, minerals, metals or gems that occur in and compose astronomical objects. It focuses on materials that may occur on the surface of or associated with some astronomical objects.
