9316474 Ralser The Grenville Orogeny is the last of several period of deformation to affect the PreCambrian rocks of Southwestern US., but is the least understood. This project will peruse several indications in existing geochronology that the effect of the Grenville is present in the form of greenschist facies shear zones in several mountain ranges in New Mexico. Results will help understand the distal effects of the Grenville an Older rocks in this area, and may provide insights into how geochronological work could clarify distal orogenic effects generally.

小行星9316474 格伦维尔造山运动是影响美国西南部前寒武纪岩石的几个变形时期中的最后一个， 但却是最不被理解的。 本项目将仔细研究现有地质年代学中的几个迹象，即格伦维尔的影响以绿片岩相剪切带的形式存在于新墨西哥州的几个山脉中。 研究结果将有助于了解该地区的格伦维尔和更古老的岩石的远源效应，并可能提供有关地质年代学工作如何能够澄清远源造山效应的见解。
