中文摘要
这个项目的主要目标是了解更多的历史 通过研究球粒陨石来研究太阳星云。 期间 在接下来的两年里,PI将:检查新的球粒陨石发现 与Renazzo和Al Rais碳质方解石相关, 继续研究新的CK组碳质方解石, 分析了一些CI类碳质矿物,并寻找其他 看起来很有异国情调的人,回到L/LL的人, 寻找证据,将解决L/LL问题, LL组。 大约30种元素将在PI的实验室进行分析, 高精度中子活化分析。 这将提供 有助于更好地理解的重要数据 太阳系的形成。
英文摘要
The primary goal of this project is to learn more about the history of the solar nebula by studying the chondrite meteorites. During the next two years the PIs will: examine new chondrite finds related to the Renazzo and Al Rais carbonaceous chondrites, continue study of the new CK group of carbonaceous chondrites, analyze some CI-like carbonaceous chondrites and search for other seemingly exotic chondrites, return to the L/LL chondrites and search for evidence that will resolve the L/LL chondrites from the LL group. About 30 elements will be analyzed in the PI's lab using high precision neutron activation analysis. This should provide important data which will contribute to a better understanding of the formation of the solar system.
