Metalloid minerals is a lecture and an article from the school of geology and the radiation astronomy department. It is about solid, crystalline substances that occur in and compose astronomical objects including the Earth. It focuses on materials containing large amounts of aluminum that may occur on the surface of or associated with some astronomical objects.
