Short summary
We have precisely determined the crystal structure of zircon, a well-studied mineral for understanding the Earth's history, up to very high-pressure conditions corresponding to the deep Earth. The averaged length of the zircon–oxygen bond showed a value consistent with the partitioning behavior of the trace elements between zircon and melt. The averaged lengths of the cation–anion bonds under high pressure can help in understanding the partitioning coefficient between minerals and melt.
