The analytical methods and experimental data to be developed will enable an Australian team to become world leaders in determining pressures and temperatures of mineral growth that correspond to a range of depths and temperature gradients in the Earth tha t is wider than accessible previously. Obtaining this information from small zones within single grains will allow determination of rates of change, and give us a detailed picture of how the host rock has evolved, even from very small samples. One application would be checking the origin of relatively common minerals for whether they could be associated with diamonds.

将开发的分析方法和实验数据将使一个澳大利亚小组成为确定矿物生长压力和温度的世界领导者，这些压力和温度对应于地球上比以前更广泛的深度和温度梯度。从单个颗粒内的小区域获得这些信息将允许确定变化率，并为我们提供关于寄主岩石如何演变的详细图片，即使是从非常小的样本。一个应用是检查相对常见的矿物的来源，看它们是否与钻石有关。
