Conclusion : Expedition 312

Here on Expedition 312, scientists are carefully examining many aspects of the cores and beginning to answer the questions, "How can we decipher the history of these ocean floor rocks? Did all the magmas come from the same peridotite? Did they form at the same pressure and temperature in the mantle? What are the chemical, magnetic, and structural relationships between the rocks? What role does water have in the formation of ocean crust or the location of the magma chamber? Can geophysical techniques be improved to help us to better understand ocean crust formation?" Hundreds of geologists around the world are trying to solve these puzzles.
