Three-Dimensional Simulations of Long-Range Pollutant Transport Using 222Rn and 210Ph as Tracers

这项资助将允许F. A. Caporuscio完成博士论文研究，他将分析来自南非贝尔斯班克和罗伯特-维克托金伯利岩的12个辉长岩包裹体样本。将完成电子探针和岩石学分析；对矿物分离物和部分整岩进行稀土元素、钡、铪的化学分析；将测定整个岩石和矿物分离物的氧同位素；并将对选定的样品进行Nd和Sr同位素分析。目的是更好地了解非洲南部古老而稳定的地壳下地幔的化学和历史。

This grant will allow the completion of PhD dissertation research by F. A. Caporuscio who will analyze 12 samples of eclogite inclusions from the Bellsbank and Roberts-Victor kimberlites, South Africa. Electron microprobe and petrographic analyses will be completed; chemical analyses on mineral seperates and some whole rocks will be carried out for rare-earth elements as well as Ba and Hf; Oxygen isotopes will be determined for whole rocks and mineral seperates; and Nd and Sr isotopic analyses will be carried out on selected samples. The purpose is to better understand the chemistry and history of the mantle underlying the old and stable crust of southern Africa.
