Early-formed rare and unique meteorites and clasts in meteorite breccias (B05+)

在这个项目的框架内，我们发现了陨石角砾岩中的富含挥发性物质的碎屑，它们不同于以前在研究个别陨石时发现的所有陨石物质。尤其是一种新类型的C1碎屑，它与依夫纳样(CI1)软骨质有显著不同。为了更好地确定这些碎屑在早期太阳系中的作用，以及它们是代表行星构造块还是晚期吸积过程的组成部分，新发现的碎屑物质将进行同位素(铬、钛和氮)和化学(主要和微量元素组成，包括惰性气体)的表征。此外，现有的样本集将通过在角砾岩中寻找新的独特类型的陨石和碎屑来扩展。

Within the framework of this project we identified volatile-rich clasts within meteorite breccias that differ from all meteoritic materials previously identified in studies of individual meteorites. This is especially the case for a new type of C1-clasts that differ significantly from Ivuna-like (CI1) chondritic matter. To better determine the role of these clasts in the early solar system and whether they represent planetary building blocks or components of late accretionary processes, the newly identified clast materials will be characterized isotopically (Cr, Ti, and N) and chemically (major- and trace-element bulk compositions, including noble gases). In addition, the existing sample set will be extended by searching for new unique types of meteorites and clasts in breccias.
