Interpreting Bowen's Reaction Series 1) What minerals would you expect to find in the following rocks? Basalt Diorite Granite Gabbro 2) You have a magma that is at a very high temperature and pressure. What minerals would crystallize from this magma if it was intrusive? What minerals would crystallize if it was extrusive? What would be the difference in these rocks? 3) Which minerals would you expect to find on a beach? 4) Why would you not expect to find olivine in a rhyolite? 5) You analyze the minerals in a rock and find that it contains only olivine. How could this happen?
