Organic Matter in the Aguas Zarcas (CM2) Meteorite: High Abundance of Aliphatic Carbon in Metal-Rich LithologyThe Aguas Zarcas meteorite is a new CM2 chondrite which fell on 23 April 2019 (local time) in Costa Rica. Aguas Zarcas is brecciated and contains several different lithologies, e.g., metal-rich lithology and CI-like lithology. This fresh CM2 chondrite gives us good op-portunities for analyses of organic matter (OM) without terrestrial contamination and weathering, particularly some stones which were collected before rain fell over the fall site. We also aim to characterize local hetero-geneities and associations of organic and mineral phases using state-of-the-art microscopic techniques to con-strain the origin and evolutionally processes of OM during pre- and post-accretion.
