In particular, mesosiderites are meteorites with a structure considered to be composed of equal parts of iron\u2013nickel metal and silicates. A natural delimitation in the study of such complex systems is the discrimination of the iron\u2013nickel metallic and silicate domains. In this work, we focus on the metallic phases of the Mincy mesosiderite, a specimen available at the Instituto de Ciencias Astron\u00f3micas, de la Tierray y del Espacio repository. In Mincy, the metallic phases are iron\u2013nickel\u2013carbon alloys that are distributed forming metallic lumps or pebbles (referred to as metallic nodules in the article) in which kamacite and taenite are present, and taenite is found both at the kamacite\/silicate interface and surrounded by kamacite, that is, isolated from the silicates. We made use of the electron backscattered diffraction technique to determine the crystallographic orientation relationships along the taenite\/kamacite boundaries as well as for characterizing the (hkl)-specific grain boundaries regarding the underlying tilt, twist, or twinning mechanism to assist the interpretation of the phase transformations and mechanisms that could explain the formation of these metallic nodules. From the results, each of the metallic nodules has a unique temperature\u2013pressure history and kinetics to undergo phase transformations (mainly partial melting, heterogeneous nucleation-controlled solidification, and possible evaporation\u2013condensation) as well as liquid-phase sintering and recrystallization in its own way.”<\/p>\n","protected":false},"excerpt":{"rendered":"
