What: "The minerals contained in rocks provide hidden clues about the conditions under which the rocks formed. A mineral is like a little fossil. It's a story of a past time. Fossils to us tell us about past living conditions and where that fossil grew and lived at a very different age, and minerals do the same thing. Like fossils, minerals in a given rock are millions, if not billions, years old, but they trap within themselves, within their own internal compositions, their own history."
