Project Title: Cliftonite formation in IAB iron meteorites as a means to understanding the genesis of non-magmatic meteorites

Brief Summary: Carbon in meteorites provides insight into the processes that took place billions of years ago in our Solar System. In this regard, carbon formations in Campo del Cielo named cliftonites may give some clues about the formation of non-magmatic iron meteorites, which is still under debate. To this aim, advanced characterization techniques (particularly EBSD, TKD, and APT) were performed at the GPM's laboratory (URN-INSA Rouen-CNRS, France) on Campo del Cielo samples from the international meteorite repository (CONICET-UNSJ, Argentina). EBSD and TKD were successful, while APT presented some difficulties that are expected to be overcome shortly to get conclusive results.
