9804874 Condie This project is an attempt to follow the process by which collisional orogens become cratonized. The study will focus on plutons and paragneisses from the internal subdivision of the Trans-Hudson orogen. The project will benefit from the Canadian Lithoprobe Seismic transect and will involve extensive isotopic age dating using minerals with various closure temperatures. Results will allow construction of time-temperature cooling curves for the several terranes and the bordering Archean cratons.

小行星9804874 这个项目试图跟踪碰撞造山带的碰撞过程。 这项研究将侧重于横贯哈德逊造山带内部细分的深成岩和副片麻岩。 该项目将受益于加拿大Lithoprobe地震断面，并将涉及使用具有各种闭合温度的矿物进行广泛的同位素年龄测定。 结果将允许建设的时间-温度冷却曲线的几个火山岩和毗邻的太古宙火山岩。
