9909231Van der VooEurasia comprises several major cratonic blocks separated by mobile belts which cover about half of the continent. While phanerozoic motions of the major blocks are relatively well defined, the tectonic evolution of Eurasia's older mobile belts remains enigmatic. This project involves paleomagnetic and geologic studies to determine the motions of major units of Kazakhstan. Results should help resolve past position of such terranes as the Ural-Mongol belt, tarim and other blocks involved in the late paleozoic evolution of Eurasia.

9909231 Van der Voo欧亚大陆由几个主要的板块组成，这些板块被移动的带隔开，这些带覆盖了大约一半的大陆。 虽然显生宙运动的主要块体是相对明确的，欧亚大陆的老移动的带的构造演化仍然是谜。 该项目涉及古地磁和地质研究，以确定哈萨克斯坦主要单元的运动。 这一结果将有助于解决乌拉尔-蒙古带、塔里木等与欧亚大陆晚古生代演化有关的地块的过去位置问题。
