PROJECT TITLE:

Chemical and isotopic characterization of Antarctic meteorites

RESEARCH SUMMARY:

My PhD project encompasses a detailed chemical and isotopic characterization of various well-preserved Antarctic meteorites, collected in the blue ice fields surrounding the Belgian Princess Elisabeth station. In this project, we aim to apply in a systematic manner the Lu-Hf and Sm-Nd isotope systems to various meteorite classes (e.g., both common chondrites and rare achondrites, incl. martian meteorites), and investigate the distribution of trace elements in those samples. For the purpose, both of bulk analysis and in-situ measurement have been used and those data will be combined to better understand. Once the trace element distribution is better understood, its effect on radiogenic age determinations will be evaluated (e.g., 147Sm-143Nd, 176Lu-176Hf). This will lead to increased insights into the recorded formation ages of specific meteorite types and their potential resetting.

FIELD SITES:

Plenty of meteorites have been collected from Antarctica, but meteorites have been also collected from hot deserts and even from our living places. In addition, Samples collected through sample return missions such as Apollo and Hayabusa are used for our study.

KEYWORDS:
