Key Points:</br> • <b>Meteorite Classification and Brecciation</b>: Aguas Zarcas is identified as a brecciated CM2 chondrite with diverse lithologies, indicating a complex formation history involving multiple components and processes.</br> • <b> Diverse Lithologies Identified</b>: The study describes five main lithologies within the Aguas Zarcas meteorite, including two distinct metal-rich lithologies (Met-1 and Met-2), a brecciated CM lithology, a C1/2 lithology, and a C1 lithology.</br> • <b>Unique Metal-Rich Lithologies</b>: Met-1 and Met-2 lithologies are new types of carbonaceous chondrites with Met-1 showing similarities to CR and CM chondrites, yet distinct, while Met-2 is more similar to CM chondrites but with an unusually high metal content.</br> • <b>Oxygen Isotope Analysis</b>: Bulk oxygen isotope compositions were measured for some lithologies, aiding in the classification and understanding of the meteorite's origins and its parent body's history.</br> • <b>Petrographic and Mineralogical Investigation </b>: The paper focuses on detailed petrographic and mineralogical analyses of the different lithologies to classify and understand the formation history of the Aguas Zarcas meteorite.
