This project aims to develop and apply a novel way to rapidly date the mineral garnet within rocks using the analytical technique of laser ablation mass spectrometry to calculate Lutetium-Hafnium ages. Garnet is the most important mineral we have to determine the depths of burial and the temperatures rocks experienced during the tectonic processes that shaped the continents. Our novel in situ laser ablation method will allow garnet to be rapidly and easily dated, permitting routine collection of large age datasets for tectonic problem solving. It will also offer a rapid means to determine ages of garnet-bearing rocks across prospective mineral exploration regions, providing explorers with key exploration data.

本项目旨在开发和应用一种新的方法，利用激光烧蚀质谱分析技术快速测定岩石中矿物石榴石的年龄，以计算镥-铪年龄。 石榴石是最重要的矿物，我们必须确定埋藏的深度和温度岩石经历的构造过程中，形成大陆。 我们新颖的原位激光烧蚀方法将使石榴石快速，轻松地定年，允许常规收集大年龄数据集的构造问题的解决。它还将提供一种快速的手段来确定整个潜在矿产勘探地区含石榴石岩石的年龄，为勘探者提供关键的勘探数据。
