9706541 Karlstrom The assembly and breakup of the Late Proterozoic super continent of Rodinia is a fundamental question of late Precambrian tectonics. Because the rock record of this time interval is so limited, studies of the well exposed rocks that do exist become all the more compelling. In a broad attack of this problem, the University of New Mexico, Harvard, and MIT will work collaboratively on late Proterozoic rocks of the southwestern edge of North America. These investigators will study the geological, paleontological, and tectonic evolution of a sequence of sedimentary and volcanic rocks of Late Proterozoic age in the southwestern US. The structural, sedimentological, geochronological, paleontological, and paleomagnetic data to be collected will bear directly on the ages and sedimentary and tectonic environments of deposition of these rocks, and at the same time examine the Late Proterozoic evolution of life prior to the Cambrian diversification of animal life.

小行星9706541 罗迪尼亚晚元古代超大陆的组装与裂解是晚前寒武纪构造学的一个基本问题。由于这段时间的岩石记录是如此有限，对确实存在的暴露岩石的研究变得更加引人注目。 为了更广泛地解决这个问题，新墨西哥州大学、哈佛大学和麻省理工学院将合作研究北美西南边缘的晚元古代岩石。 这些研究人员将研究美国西南部晚元古代沉积岩和火山岩序列的地质、古生物和构造演化。 所收集的构造、沉积学、年代学、古生物学和古地磁学资料将直接关系到这些岩石的年龄、沉积和沉积构造环境，同时也将考察寒武纪动物生命多样化之前的晚元古代生命演化。
