Evaluation of deep Earth resources requires knowing how long geological processes took, some record of which is often preserved by gradients in the chemical compositions of minerals. Experiments at very high temperatures and pressures will determine how this evidence can be used to constrain the durations of a rich variety of geological processes.

对地球深部资源的评估需要了解地质过程需要多长时间，其中一些记录通常通过矿物化学成分的梯度保存下来。在非常高的温度和压力下进行的实验将决定如何利用这一证据来限制各种地质过程的持续时间。
