The facts on the card
The card carries these facts from its Wikipedia article.
- Knowledge of the redox conditions at which a rock forms and evolves can be important for interpreting the rock history.
- Iron, sulfur, and manganese are three of the relatively abundant elements in the Earth's crust that occur in more than one oxidation state.
- For instance, iron, the fourth most abundant element in the crust, exists as native iron, ferrous iron, and ferric iron.
