We propose the completion of a Crustal Formation Age Map for the Grenville Province. This work uses Nd isotope analysis to estimate the time when different segments of the Canadian Shield were first created as microcontinents above subduction zones. These microcontinents were subsequently amalgamated together in collisional orogenies, (ancient mountain belts) to form the continents as we know them.

我们建议完成格伦维尔省的地壳形成年龄图。这项工作使用Nd同位素分析来估计加拿大地盾不同部分首次在俯冲带上方形成微大陆的时间。这些微大陆随后在碰撞造山运动（古山带）中合并在一起，形成了我们所知道的大陆。
