Comprehensive report of the BELARE 2022-2023 meteorite reconnaissance expedition in the Sør Rondane area, East Antarctica
We provide a comprehensive overview of a reconnaissance expedition aimed at identifying new possible meteorite stranding zones in the surrounding of the Belgian Princess Elisabeth Antarctica (PEA) station in the Sør Rondane Mountains during the BELARE 2022-2023 field season. The team was composed of...

In addition, nine surface ice samples and 18 kg of micrometeorite-bearing sediments were collected. Preliminary classification, performed on-site using magnetic susceptibility, tentatively indicated H and L chondrites. The recovered meteorites were transported in frozen state to the Royal Belgian Institute of Natural Sciences in Brussels to be thawed in vacuum conditions and classified based on their mineralogy.
