We estimated a petrologic type for our sampled CM lithology using the two independent techniques, and obtained a type CM2.5, in agreement with previous estimations. By comparing the Si-O 10-\u00b5m signature of the AZ average FT-IR spectra with other well-studied CMs, we place AZ in the context of aqueous alteration of CM parent bodies. Morphological characterization reveals that AZ has heterogeneous distribution of pores and a global porosity of 4.5\u2009\u00b1\u20090.5\u2009vol%. We show that chondrules have a porosity of 6.3\u2009\u00b1\u20091\u2009vol%. This larger porosity could be inherited due to various processes such as temperature variation during the chondrule formation and shocks or dissolution during aqueous alteration. Finally, we observed a correlation between 3D distributions of organic matter and mineral at micrometric scales, revealing a link between the abundance of organic matter and the presence of hydrated minerals. This supports the idea that aqueous alteration in AZ\u2019s parent body played a major role in the evolution of the organic matter.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Z\u00e9lia Dionnet, Alice Al\u00e9on-Toppani, Rosario Brunetto, Stefano Rubino, Martin D.
